Svantek SV 977C
Sound & Vibration Level Meter

The kit consists of SVAN977C Class 1 sound & vibration level meter with a detachable preamplifier SV 12L and high quality MK 255 microphone. The list of accessories includes: SA 143 carrying case, SA 22 windscreen, 16 GB microSD card, four AA batteries, USB cable and 36 months warranty card upon product registration.

Svantek SV 977C Sound & Vibration Level Meter

The SVAN 977C is a Class 1 Sound and Vibration meter designed for building acoustics, occupational noise and environmental noise measurements. The meter is a successor of SVAN 977A offering new 1/2” microphone MK255 offering wide frequency range from 3 Hz and excellent long-time stability of sensitivity.  The SVAN 977C has a built-in Bluetooth® interface for wireless connection with with smart-phone applications like Building Acoustics Assistant that extends measurement capabilities dedicated for building acoustics.

One unique feature of the SVAN 977C is ultrasound measurement band up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Ultrasound is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures.

The SVAN 977C can be also used as the vibration level meter – simply by connecting a cable and a vibration sensor.

1/1 and 1/3 octave on board!

frequency analysis, ultrasounds, wave recording

FREQUENCY ANALYSIS of the signal in 1/1 or 1/3 octave bands allows to determine the influence of high or low frequencies on overall values. With an optional microphone SVAN 977C provides analysis of the ULTRASOUNDS up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Limits of permissible ultrasound levels are usually expressed in terms of Leq and Max values specified in 1/3 octave bands for 20 kHz, 25 kHz, 31.5 kHz and 40 kHz. SVAN 977A also offers options for time domain signal recording – recording the raw signal samples with defined frequency up to 48 kHz. Post-processing of high quality wave files (48 kHz, 24 bit) such as calculation of tonality is available in SvanPC++ program.

Occupational Noise

Noise measurements at work places

SVAN 977 can be used for measuring workers’ exposure to noise in a working environment in accordance to international and local standards such as ISO, OSHA etc. The instrument provides A-weighted and C-weighted levels as well as audio recording for noise sources recognition and 1/1 octave for selection of hearing protectors. The evaluation of results is supported by dedicated Supervisor software, that provides with ready reporting templates. Additional advantage is the ultrasound measurement capability that is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures
