SV 973

Sound Level Meter

About

SV 973 is a Class 2 sound level meter with a wide frequency range up to 10 kHz. The unique feature of the SV 973 is the microphone in MEMS technology with a lifetime warranty. The meter’s measurement range from 25 to 128 dB enables its use in industrial and environmental noise measurements.  For measurements of noise at work, the intelligent sound exposure meter function limits the frequency range to 10 kHz and shifts the dynamic measuring range of sound level meter to 141 dB Peak. The instrument is easily calibrated in the field using an acoustic calibrator as the calibration begins automatically when the microphone is inserted into the calibrator. The SV 973 can measure broad-band results with all the necessary weighting filters as well as 1/1 octave or 1/3 octave band filters. Audio events recording function works together with sound level meter mode. The data are stored on built-in 8 GB memory and can be easily downloaded to a PC using the Supervisor or SVANPC++ software.

Features

MEMS technology microphone

a life-time warranty for the MEMS microphone

SV973 Sound Level Meter is equipped with an innovative microphone that combines two MEMS microphones in one 1/2 "housing. This solution allowed to obtain two measuring ranges, with a total value from 25 dBA up to 141 dBA, in the frequency range up to 10 kHz. Using MEMS technology, the ST 973 microphone is resistant to mechanical shocks and consumes less energy, which translates into an extremely long battery life, up to 38 hours! Like other Svantek MEMS microphones, the ST 973 is covered by a lifetime manufacturer's warranty.

Extended analyzer functionality

1/1 and 1/3 octaves, audio recording, RT60 and STIPA

Due to its measurement capabilities, SV973 Sound Level Meter is one of the best class 2 meters available on the market. Analyzer options such as 1/1 and 1/3 real-time octave analysis, audio recording, reverberation time measurement, and even STIPA speech intelligibility significantly exceed the capabilities offered by other class 2 meters, and in many cases class 1 meters.

Smartphone application

mobile application extending the capabilities of the meter

SV 973 has been equipped with a Bluetooth communication module, thanks to which it will be able to establish a connection with the Assistant mobile application (under development). The mobile application extends the possibilities of the meter, giving the possibility of viewing the results on a larger screen and the ability to control the measurement (e.g. start / stop). In addition, the application will help to perform STIPA or RT60 measurements. The application is under development.

Applications

Occupational Noise

noise measurements at work places

The meter’s measurement range enables its use in industrial and environmental noise measurements. For measurements of noise at work, the dedicated sound exposure meter function shifts the dynamic measuring range of sound level meter up to 141 dB Peak. The instrument is easily calibrated in field using an acoustic calibrator as the calibration begins automatically when the microphone is inserted into the calibrator.

Sound Measurements

Measurements in the frequency range up to 10 kHz

The SV 973 complies with the requirements of class 2 in accordance with IEC 61672, so it can be used for all types of measurements where the class 1 frequency range is not required, up to 10 kHz.

RT60 and STIPA

Measurements of speech transmission index and reverberation time

The SV 973 is equipped with a STIPA and RT60 module, thanks to which it can be used in applications where it is permissible to use class 2 meters for measuring the STIPA speech transmission and RT60 reverberation time. For both measurements, the procedure is supported by the BA Assistant mobile app (under development), which guides the user through the measurement and offers reporting options.
