We stock a wide range of accessories, order what you want and only pay for what you need
Sound level meters and particularly microphones are very susceptible to damp, so should not be used outside, unless protected - see our environmental kits.

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 - ideal for survey work ****.
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

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. 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 LpeakMulti-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
* Our standard hire charges are based on a 4-day minimum period, details other options.
