Sound Level Meter Set PCE-428-EKIT-ICA

The aircraft noise meter PCE-428-EKIT consists of two components: The noise meter PCE-428 and the outdoor measuring kit PCE-4xx-EKIT. In this combination of components, this aircraft noise meter is ideal for permanent noise level monitoring at airports, approach lanes in residential areas and wherever aircraft noise needs to be monitored.
The PCE-428 Aircraft Noise Meter meets all the requirements of Class 2 sound level meters. It is equipped with an octave band filter for frequency analysis. Optionally, this frequency filter can be upgraded to a 1/3 octave band filter. Thanks to the integrated memory or data logger function, the aircraft noise meter can log the measured values over a set storage interval. The measuring range of the aircraft noise measuring device extends from 25 ... 136 dbA at a frequency of between 20 Hz and 12.5 kHz. The Aircraft Noise Meter has various automatic measuring functions such as Leq, Lmax, Lmin, Lpeak ... For frequency evaluation, the basis of evaluation A, B, C and Z are always available as standard in the aircraft noise meter. The display is able to show the measured values of the aircraft noise meter numerically with bargraphs or graphically.
As a special feature, the aircraft noise meter is supplied with a waterproof kit for permanent outdoor use. This outdoor kit ensures that the sound level meter can be safely used even in bad weather conditions. The measuring kit of the aircraft noise measuring device consists of a waterproof plastic case with charging unit and additional batteries as well as special wind and rain protection for the microphone of the PCE-428. During the complete aircraft noise measurement, the sound level meter can remain in the suitcase. The additional batteries from the aircraft noise meter ensure that a measurement of 10 days at a time can be performed. The charger, which is included in the outdoor kit, is also IP65 protected and can thus remain outside of the case during operation, so that much longer runtimes are possible from the aircraft noise meter.
The evaluation software of the aircraft noise measuring device can be used to evaluate how often and when certain sound events have occurred. For this purpose, the software simply enters the aircraft noise threshold and the software evaluates the complete acoustic measurement cycle in tabular form and displays only the corresponding sound levels with time and date stamp.
