Sound Insulation and Building Acoustics using the Nor 118 +

The Nor 118 + Real Time Sound Analyser includes an internal noise generator and the circuits to measure the room noise levels and calculate the reverberation times. Sound Insulation Ratings are then made using the tables in the relevant Standard(s) ****.

To use your own amplifier/speaker system, just add a Nor 4514 noise output cable and a tapping machine if required.

Alternatively we hire sound insulation kits at special rates - the analyser comes at half price.

Sound Power Measurements using the Nor 118 +

All the Gracey & Associates Nor 118 + precision sound analysers are fitted with the.

Option 9 : Reverberation time calculations

Option 10 : Sound Power Mode

and therefore suitable for measurements of the following parameters

Engineering and Survey measurements of the LwA - A-weighted sound power levels

Sound power measurements according to BS 4196, BS EN ISO 3746

CE-marking of new products

Nor 118 + Sound Power Measurements	£ 32 a day *

Features

Up to 40 microphone positions.

Selection of 6 hemispherical or parallel-piped surfaces.

Correction for background noise and for the acoustic environment.

Frequency analysis to establish flat or A-weighted spectrum.

Checks for possible impulsive noise and the directivity.

Also measures the C-weighted Lpeak

A class 1 Sound Calibrator is also recommended.

Multi-spectrum Measurements using the Nor 118 +

The multi-spectrum option allows even more sophisticated measurements. This upgrade of the time profile permits complete spectra to be measured as a function of time - not just broadband. You may then track a given frequency band as a function of time or inspect the spectrum at a given moment in time. You can even record the 1/3-octave statistics for each period of time within an overall measurements - providing full information for enhanced environmental noise surveys
