Sales Training Note NorReview version 2.0 New Features This Sales Training Note describes the new features that become available when upgrading the NorReview version 1.4 to the new version 2.0. Views Vector graphic exports to other documents All the available graphs in the NorReview software are now exported as vector graphics into Word documents. This change from the earlier bitmap export greatly improves the quality of the graphs when printing out final Word reports on high resolution color printers. This improvement even holds for other copy paste operations. 1/1-octave spectrum In the “Summary” and “L(t)+L(f)” views, measured 1/3-octave spectrum may now be recalculated and displayed as a 1/1octave spectrum. This feature is enabled by selection the “Recalculate 1/3-octaves into 1/1-octaves” found in the lower left corner of the L(f) View Properties dialog. Displaying a higher number of measurements Maximum number of measurement files in an L(t) View has been increased to 50 in order to display repeatable or synchronized measurements from Nor118 more easily. The maximum number of functions per measurement is 4. The recalculation process make energetic averages of all 1/3octaves within each 1/1-octave for the Leq and LE measurement functions, and it assumes that the highest Lmax or Lpeak value for the three 1/3-octaves is the corresponding value for the recalculated 1/1-octave. For Lmin, the lowest value of the three 1/3-octaves is used. Frequency spectrum function The “L(t)+L(f)” views present the frequency spectrum of one selected measurement function in the lower level vs. frequency part. The selection of the desired function is now improved. Simply right-click the desired function in the rightmost upper part of the screen and click the “View Spectrum” in the displayed context menu. The graphical frequency spectrum in the lower part will then automatically change to this particular measurement function provided that frequency data of the selected function are available in the measurement file itself. STN 1026 v2.0 Ed.1 Rev.0 English 04.06 Recalculated 1/1-octave spectrum based on 1/3-octave measurements STN 1026 v2.0 Ed.1 Rev.0 English 04.06 AC-View When making impulsive noise measurements, it is sometimes important to view the AC-waveform of the recorded signal. Based on Nor121 recording files, the NorReview now opens the possibility to view these recordings as “AC-Views”. Simply click the cursor onto any recording along the upper x-axis of the L(t) or L(t)+L(f) Views, select the File/AC-View feature in the menu bar, or hit the key in the toolbar, and the AC-View graphical display will presented on screen. The y-range is set to 100% of selected input amplifier range as default, but may be adjusted using the Y-range selector to a lower value on demand. The new feature is selected in the Properties/Axis menu available by a right-click on the y-axis. Click the “High/Low” tag to activate the new feature. Default properties When using this new AC-View in combination with the special NorReview media player feature (option 4), the xaxis cursor will move along as the recording is played. When setting “View/Default properties”, also the window size, position and layout of the possible sub-windows are now saved for use in the next window, or next time the NorReview software package is started. Improved L(t) Legend The L(t) legend feature is enhanced to include all the marker text on two lines. Hence, longer marker names may now be displayed. AC-View diagram from Nor121 recording file High/Low compression When a larger part of the measurements are viewed on the screen, each pixel on the screen is normally shown as a compressed calculated pixel value dependant of the function (i.e. several Leq-samples are calculated into one single Leq value). When the compression is high, this means that some details are lost in the graphical presentation. Hence, a new feature for showing the compressed pixel as a “Max/min” vertical line between the highest and lowest values is introduced in the L(t)-Views of the NorReview software. The L(t) legend includes marker names with up to two lines. Tool tips in the L(t) Views The L(t) View now contains an extended tool tip information box when the cursor is placed above one of the displayed curves. High/low compression feature in L(t) views Tool-Tip box appears after placing cursor onto the measurement time 2 STN 1026 v2.0 Ed.1 Rev.0 English 04.06 Axis Y-range combo box selection Secondary Y-axis in L(t) Views The Y-axis ranges are selected in the Properties/Axis context menu, or, by clicking the desired range in the Y-range combo box after clicking the desired range in the combo box, the NorReview will now change to the selected range without the need to hit the Enter key. When noise measurements are combined with other kind of parameters, such as weather data, it is often desired to view the noise level versus time in combination with these other parameters. One example is long-term Nor121 measurements in combination with a weather station. As the weather parameters mostly have other max/min levels and ranges than the noise levels, a secondary y-axis is now available for these parameters. The desired y-axis, named A or B, is selected in the Properties/Functions context menu. Graph title and axis descriptors All the different views in the NorReview may now get titles and axis descriptions. The axis descriptors are available for the X-axis as well as for both the Y-axis A and Y-axis B. These character strings are selected and edited in the Properties/ Axis dialog. Along the right y-axis, the upper limit of both y-axes may be scrolled to fit the measured values. The ranges for the two yaxis are selected in the Properties/Axis dialog. Graphs title and Y-axis descriptions are both in the Properties/Axis dialog Individual Y-axix selection (A or B) for each measurment function Level offset In the File/Properties/Offset dialog (right click on the measurement file in the project tree), the NorReview now offers the possibility to adjust the levels of the measurement data by a given dB-value. This is useful when the measured levels contain an undesired offset such as a wrong sensitivity calibration of the instrument. It should be noted that the offset level will influence all measurement values within the measurement (i.e. all reports and all measurement functions). L(t) View with primeray Y-axis (left) and secondary Y-axis (right) Y-axis autoscaling feature The new auto scale feature is working both on the L(t) and L(f) Views, but only on the last activated part. It is activated in the View/Auto scale Y-axis menu, or, by clicking the Auto scale Y-axis toolbar button “Go To” x-axis position For the L(t) Views, the auto scaling feature is using the possible measured LAF(Max) and LAF(Min) from the overall “Global” measurement as references The upper limit will be automatically set to next 5 or 10 dB value, while the Y-range will be set to the difference between these two reference values rounded upward to the next 20 dB. Should any of the reference values not be available, the automatic scaling of the upper limit and/ or the y-range will not be adjusted. For the L(f) View, the similar auto scaling is based on the highest and lowest displayed value independent of measurement function. In the “Edit/Go To” dialog, it is now possible to select whether to center the graph on the selected cursor position or to set the left-side axis of the graph equal to the selected cursor position. 3 STN 1026 v2.0 Ed.1 Rev.0 English 04.06 Events Exclude detected events from calculations By clicking a new feature in the Event Analysis menu, the detected sources may now be marked with an “Exclude from calculation” marker”. This prevents the found marked source to be used as basis for other calculations later. Analysis with up to 5 combined conditions. Weather data as basis for the event analysis Analyzing environmental measurement sometimes require to exclude time intervals that have disturbing elements, such as too high wind, rain, etc. And often are these elements a combination of requirements. The new version of NorReview opens up the possibility to perform event analysis based on a combination of multiple conditions. A further improvement to the event analysis capabilities of NorReview, is the possibility to use weather data as basis for inserting new markers. Hence, it is now possible to insert exclude markers for time intervals where the wind is higher than a predefined speed, or the wind direction is between 135 and 225 degrees. An example of this would be to exclude the parts of a long term measurement in which the wind is above 6 m/s, or above 3 m/s if it comes from the north. Using the new feature is NorReview as indicated in the attached menu would solve this problem before the final calculations. Max/delta feature The event analysis feature has been enhanced with a new mode called “Max. Delta”. This feature search for the maximum sample within a predefined source, and insert a new marker from this highest sample and to a predefined “Delta” value in dB’s both on the left and right side of the highest sample. The “Delta” value may be specified individually on both sides. This new event analysis method is useful for finding the correct duration of fly-over noise from airplanes, or for calculating sound exposure values of other sources. Reports Word Document template The template used for the “Summary Sheet” is improved. It now contains fields for most of the standard reported issues in a noise measurement report. Some of these are pre-written with the available information from the actual measurement file (such as the used microphone sensitivity). The user may change the template with another logo or other items on demand. The same basic template is used both for the summary sheet and any other word document generated from the NorReview software package. Event extensions When performing threshold based event analysis, very short events may be marked as “Single” markers instead of a “Toggle” marker with duration of more than one sample. If the user likes to get all possible markers as “Toggle” markers, this can now be achieved by adding a predefined number of samples before and after the found source. “Coloum-breaks” in calculation tables The NorReview now automatically insert “Column-breaks” when doing “Generate Word Document” or “Add To Word Document” from the calculation result window if the resulting table gets too wide for the new Word document. 4 STN 1026 v2.0 Ed.1 Rev.0 English 04.06 Markers Marker management window In measurement project where a large number of different source markers are in use, it is sometimes difficult to keep the overview of the individual markers. NorReview has simplified this problem greatly by introducing a “Marker Management” feature. This new table may be turned on and off on demand from the View/Marker Management menu, or by clicking the “Marker Management Window” toolbar button. The window may be resized and moved to any position in the screen. Selectable lists of “Recent Markers” The “Recent Marker” list helps the NorReview users to speed up the process of marking a measurement file with repeatable noise sources. However, when the measurement objects are changing to completely different kind of sources, the recent marker list may easily contain markers with wrong names. This problem is now greatly reduced with the new feature of saving and recalling individual “Recent Marker” list. Hence, different lists named Traffic Noise, Industrial Noise, Urban Noise, etc. may be loaded dependant on the actual measurement objects. The “Marker Management Window” is build up as a project tree showing all marked sources in the measurement file, including recordings and event files from the Nor121. Each marked source contains information about the marked interval and the effective duration of the source. The window also contain the overall effective duration and number of similar sources for each marker. Groups of similar markers, or individual markers, may be excluded from the entire measurement directly in the table window. Just right-click the desired marker, or marker group. There is also a link between the individual marker and the corresponding area in the L(t) Views. Hence, the user may quickly scroll through all the marked sources, either form the graph or from the table, and immediately see the corresponding row or area in the other window. The new feature also greatly simplifies the possibility to delete entire groups of markers, or, edit the color of an entire group. Save and load of “Recent Marker” lists is possible from the “Marker” menu. Marker management window with all individual markers from the L(t) View 5 STN 1026 v2.0 Ed.1 Rev.0 English 04.06 Files After the concatenating process, the same directory will contain this new measurement file (.nbf) named in accordance with the operators instructions. It should be noted, though, that the concatenating process will only function on those measurement files which have exactly the same instrument setup as the first measurement file in the selected range. Files which do not comply will be left out from the final concatenated file. Import of measurement directories It is now possible to drag&drop one or more directories into the NorReview project tree. In this case, the program will scan the directories for all available Norsonic measurement files. This is a very convenient way of putting one or more Nor121 measurement directories into a project. Concatenating repeated Nor118 measurements When the Nor118 instrument is used for environmental noise monitoring, the operator often prefer to let the instrument measure a “Global” duration of typically 30 minutes or 1 hour with a predefined “Profile” resolution at 1 second or similar. The Nor118 is normally set to “Repeat” or “Synchronized” memory storage, meaning that the Global measurement durations are stored sequentially over a total period of 24 hours, or even longer. In previous versions of NorReview, all these measurement files had to be opened one by one, and only 4 of them were displayed simultaneously. L(t) View of concatentaed Nor118 file This new concatenated file may now be imported into the NorReview project tree just as with any other measurement file. The L(t) View will then show all the single measurement sequentially with a small time gap in between due to the fact that the Nor118 uses some time to save and restart each individual measurement. The marker insertion and calculation processes within NorReview will, however, handle these time gaps just as any other “Exclude” marker (or measurement pauses). Additional measurements into an L(t) View A new quicker way to add a measurement file into an existing L(t) View, is to drag&drop the desired additional measurement from the project tree and directly onto an existing L(t) View. Files selected for concatenating process The new basic version of NorReview greatly improves this as it is now possible to concatenate multiple measurement files into one single measurement file. The operation itself is controlled from the NorXfer dialog, although the function is only available when the NorReview software is installed on the same PC. The selected files are marked out in the rightmost NorXfer window, right click the mouse and select “Concatenate” in the menu. The user may then predefine the name of the new concatenated file. Online noise monitoring into L(t) Views The version 2.0 of the NorReview is prepared for connection directly onto a SQL database with noise monitoring results. This will get handy with the upcoming new releases of NorMonit 3.0 software for multi positions environmental noise monitoring. Measured noise level will be displayed live in a special “QuickView” level vs. time graphical window. This feature combined with the continuously recording capability of the NorMonit 3.0 feature will allow the user to listen to the noise signal at any time along the time line of the presented noise profile. Special concatenated measurment file based on selected files 6 STN 1026 v2.0 Ed.1 Rev.0 English 04.06 Calculations The answers are found under the QuickCalc tab “Percentiles” together with the normal percentage calculations. Exceedance level The user additionally has the choice to displaying a light red background color in the L(t) View indicating the levels that are above the set exceedance level. This choice is set in the lower left corner of the Properties/Axis dialog. The Quick-Calc features have been enhanced with a new calculation called “Exceedance Level”. By entering a dB-value as the desired exceedance level in the Tools/Options/Percentiles menu, the NorReview now calculates the percentage of samples within any cursor-selected area that exceeds this given threshold value. Calculation of weather data The optional calculation module is now enhanced to perform Average, Max and Min calculations for weather data. Calculation of national Italian environmental Standard The optional DM160398 module is now improved based on the latest ISO 226 hearing threshold values. Additionally, the post processed values are now taken only from the non-excluded parts of the overall measurement. L(t) View and tabular display of selected exceedance level Tonality calculation according to German DIN45681 Standard An new optional feature for calculation of the tonality content of a noise source is introduced. The new feature is based on the recently released German DIN 45681 Standard from late 2005. It require audio records made with the Nor121 instrument as basis for the calculation which initially performs a special FFT analysis and then calculates the correction of the overall noise level based on the tonality content of the FFT analysis. Overall source calculations When doing “Overall” source calculation, the number of sources found in the actual time interval is now displayed together with the “Effective duration” in the calculation result window. Calculations result window inclueds the numer of individual sources. 7 STN 1026 v2.0 Ed.1 Rev.0 English 04.06 The different features within the NorReview are available in batches, or options. Some of the basic features come with the basic package, and some of the more advanced features come with the individual options. In the new version 2.0 there has been a re-organization of the different features in order to make the different optional packages more useful and easier to understand. This means that even the basic package now contains more features than earlier.
