Description

SVANTEK SV 971A

Class 1 Sound Level Meter

 

The SV 971A Class 1 sound level meter is designed for occupational noise and building acoustics measurements. The type 1 noise meter uses a microphone offering a linear measurement from 27 to 140 dB in a single range. For ease of use the sound level meter uses dedicated mobile applications, that support sound measurements as well as RT60 and STIPA.

 

What is a Class 1 Sound Level Meter?

A Class 1 Sound Level Meter is a sound measuring instrument that meets the IEC 61672-1:2013 (or equivalent BS EN 61672-1:2003 or DIN EN 61672-1:2014) standard’s performance criteria such as linear operating range, frequency response, and temperature operating range.

 

How do I choose a sound level meter?

Know the measurement standard: ISO, OSHA, MSHA, ACGIH

To choose a sound level meter, you need to know the measurement standard (ISO, OSHA, MSHA, and ACGIH) that will tell you exactly what type of sound level meter you need. The SV 971A meets the performance criteria of IEC 61672 and is equipped with a new measuring microphone that offers an LAeq linear measurement range from 27 to 137 dB (140 dB Peak) in a single range! This provides an accurate response to sound pressure measurements for noise at work, as well as basic environmental measurements with external microphones.

 

Applications

Occupational Noise
ISO, OSHA, MSHA, and ACGIH guidelines

The class 1 sound level meter new design meets an international standard IEC 61672 and ANSI/ASA S1.4 standards in the United States. It is accurate for noise measurements in line with ISO, OSHA, MSHA, and ACGIH standards for industrial hygiene noise measurements to prevent hearing loss. With a noise dose meter enabled, both noise dose and noise exposure are calculated.

Sound Insulation
Sound insulation measurements following ISO 16283

Along with the new hardware additions, the SV 971A has a new internal program that supports RT 60 reverberation time measurement and STIPA speech intelligibility measurements, both supported by a mobile application.

STIPA Voice Level Meter
Speech transmission indexes for public address systems

In organizing STIPA measurements and calculations, the meter is supported by a dedicated mobile application. The STIPA signal is usually reproduced by loudspeakers available in the public information system under study, and in some cases, dedicated loudspeakers are used.
