Nor118 Sound Analyzer

Nor118 Sound Analyzer

Description

Nor118 (hardware obsolete but software options still availalable and supported !)
Option 01 : 1/1-octave band filters - real time
Parallel 1/1-octave band, real time filters, 8 Hz - 16 kHz

All filters fulfil the IEC 61260 class 1 digital IIR base 10 requirements

120 dB 'one-range' in all filter bands

Graphical and numeric display

A-weighting [pre-weighting] feature available on displayed results

Option 03 : 1/3-octave band filters - real time
Parallel 1/3-octave band, real time filters, 6.3 Hz - 20 kHz

All filters fulfil the IEC 61260 class 1 digital IIR base 10 requirements

120 dB 'one-range' in all filter bands

Graphical and numeric display

A-weighting [pre-weighting] feature available on displayed results

Option 04 : Calculation of Ln statistical values
Calculates 7 fixed Statistical Ln values L1%, L5%, L10%, L50%, L90%, L95% and L99%

Parallel calculation of 1 editable Ln, selectable within the range 0.1% - 99.9%

Statistical calculations based on 0.2 dB class widths covering the entire 120 dB dynamic range

Parallel statistical calculations on both A and C/Z-weighted networks

If the real-time filters are installed (options 1 and 3) the statistical values calculated for the individual filter bands are available as well

Option 06 : Level versus Time measurements
Selection of preset intervals within the 1 second to 99 hours interval range

Automatic level versus time storage of LAeq, LAmax, and LCpeak or LZpeak

Level versus time measurement continues during a paused Global measurement

Markers identify any pause, stop or continuation of a measurement

Real-time graphical and numeric display of the level versus time results

Simultaneous measurements of Global results i.e. all measured data described for the basic instrument including any of the above options and Profile results based on level versus time values at preset intervals

Option 07 : STIPA

Speech Transmission Index mode for measurement of the STIPA index according to IEC-60268/16. Includes Nor1034 CD with STIPA excitation signal. (Requirex option 1).

Option 08 : Multi-spectrum measurements
Automatic level versus time storage of Lfeq and Lfmax for each frequency band in addition to the LAeq, LAmax and LCpeak or LZpeak

Option 09 : Reverberation Time measurement mode
 Reverberation time measurements based on impulse or noise [option 17] excitation

Calculates both T20 and T30 based on backward integrated decay

Results presented in graphical and table format for all frequency bands

Covers 63 Hz - 8 kHz in 1/1-octave bands

Covers 50 Hz - 10 kHz in 1/3-octave bands

If option 17 is installed then RTs may be measured using noise excitation

Option 10 : Sound Power measurements - survey method
 Calculates the survey grade LWA sound power level based on multiple measurement positions on a theoretical hemisphere above a noise source placed on a reflective floor

Automatic correction of background noise level

Fulfills the requirements of BS EN ISO 3746

Option 16 : Measurement Trigger
Trigger the measurement start based on the internal clock, level threshold or external TTL signal

Level threshold trigger used in combination with Repeat storage makes an automatic even measurement device

Option 17 : Noise Generator
 Produces white or pink noise excitation signals

Noise output signal adjustable

Noise signal synchronised with start and end of measurement sequence
