Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

chevron_right

A microphone calibration system for determining the level linearity and harmonic distortion of measurement microphones and pressure sensors. The system, Type 9719, applies a specially designed high-pressure, low distortion measurement chamber that can generate very high sound pressure levels.

Type 9719 is a specially designed system for determining the dynamic linearity and distortion of measurement microphones and pressure sensors. The output signal of the microphone under test is compared to the output of a high-pressure microphone mounted in the measurement chamber, while the sound pressure is increased in steps of 1dB or more, until the desired sound pressure level is reached. The rms, negative peak and positive peak values and the distortion are recorded for each level step. The maximum sound pressure level of the system is 171dB rms.

USE SCENARIOS

Level linearity calibration of microphones, pressure sensors and sound level meters
Linearity calibration from medium to high pressure levels
Harmonic distortion measurements

FEATURES

Linearity calibration by comparison with high-pressure monitor microphone (IEC 61094-5)
Determination of 2nd, 3rd and total harmonic distortion
Calibration levels from 94dB to 171dB rms (14µBar to 0.1Bar peak) @ 500Hz
Distortion of the high-pressure sound source is max 0.5% @ 171dB rms level
Fast, automated measurement, printing of calibration certificate and data export to Excel
