Acoustic Dose Measurements Using Microphone-in-real-ear Technique With Sv 102

SVANTEK (Poland) announces the introduction of the completely new,
dual-channel, acoustic dosimeter SV 102 with dual-channel real-time
1/1 octave analysis. Instrument presents completely new approach to
occupational health and safety acoustic monitoring task. The binaural
dose measurements and 1/1 octave analysis are simultaneously performed.
Octave analysis provides direct data for the design of the ear-protectors.
Together with audio-events-recording option, these functionalities show
the new reference standard on acoustic dose measurement fields, now commonly available in compact size instrument.
Dosimeter is offered with one or two dedicated SV 25D ceramic
microphones in ½” housing. It ensures the very easy calibration by direct usage of commonly available acoustic calibrators. Moreover, SV 25D smart sensor, with built-in TEDS (Transducer Electronic Data Sheet),
offers automatic calibration function.
The very robust casing of SV 25D, together with the special mounting
clip and dedicated headband, make that microphones can be very easy
attached in extremely short distance from the human ears.
SV 25S smart sensor with TEDS, dedicated for the measurements
under headphones or earmuffs using MIRE technique (Microphone-In-Real-
Ear), is under development and will be available soon. SV 25S microphone, using special adapter, can be also calibrated with commonly available acoustic calibrators.
Advanced time-history logging for each profile, together with spectra
saving and audio-events recording provide complete information about
measured signal, which is saved in non-volatile internal memory (up to 64 MB) of the dosimeter. Data files are easy downloaded to PC using USB
interface and SvanPC+ software.
