Indoor noise monitoring station
110 dB, 12 - 48 kHz | SV 215 SVANTEK Sp. z o.o.

The SV 215 is an acoustic monitoring case dedicated for the indoor use. The main applications include the residential area indoor noise monitoring, the audio performances monitoring and many other cases when a justification of the annoying noise has to be measured and identified.
The main feature of this set is the long term continuous sound level logging (Leq and optional 1/3 octave levels) with a unique capability of the simultaneous Audio Events Recording (AER). The AER is essential for identification of the related sound source by the playback. The AER trigger mode can be set up as manual (audio recording is started by radio remote control, switchable on up to 50-meters distance) or automatic (audio is recorded when measured Leq is, for example, above certain level).
The AER time is user programmable as well as the sampling frequency which can be selected to 12 kHz, 24 kHz or 48 kHz (12 kHz sampling rate provides lower quality audio signal but allows the longer audio recording, whereas 48 kHz sampling frequency provides excellent audio signal quality but the recording time is trice reduced comparing to 12 kHz recording mode). The AER function also provides the pre-trigger recording whose period depends on the selected sampling rate and it is 4 seconds in case of 12 kHz, 2 seconds in case of 24 kHz and 1 second in case of 48 kHz.
