Svan 977D

Sound & Vibration Analyser

The SV 977D is a Class 1 Sound and Vibration meter designed for building acoustics, and occupational and environmental noise measurements. The meter is equipped with a 1/2” MK 255 microphone offering a wide frequency range from 3 Hz and, excellent long-term stability of sensitivity. The SV 977D has a built-in Bluetooth® interface for wireless connection with smartphone applications such as Building Acoustics Assistant which extends the measurement capabilities dedicated for building acoustics. The SV 977D can also be used as a vibration level meter by simply connecting the appropriate cable and a vibration sensor.

Wide application

Key Features

Class 1 sound & vibration level meter – The SV 977D Class 1 Sound & Vibration Level Meter and Analyser is designed to meet the needs of both environmental monitoring and occupational health and safety monitoring specialists.
Real-time frequency analysis – Depending on the application, frequency analysis can be done in the 1/1 octave, 1/3 octave spectra or optionally in FFT.
WAV recording – Optional time domain signal recording to WAV format with a defined frequency up to 48 kHz. Postprocessing of high quality wave files (48 kHz, 24 bit) is available in SvanPC++ program.
Reverberation time measurements – The RT 60 functionality in the instrument provides fast verification of results on site. Calculation of RT 60 values is based on 1/1 or 1/3 octave logging results. The smartphone application helps the user in calculating the insulation in accordance with ISO 16283.
STIPA in accordance with IEC 60268 – The meter is supported by a dedicated mobile application to help perform STIPA measurements and calculations. The STIPA signal is usually reproduced by loudspeakers available as part of the public information system under study, and in some cases dedicated loudspeakers are used.
Ultrasounds to 40 kHz – With an optional microphone and 1/3 octave or FFT analysis, the SV 977D provides analysis of ultrasounds up to 40 kHz.
Vibration level meter – If you disconnect the microphone preamplifier, you can use the instrument to take vibration measurements by simply connecting the appropriate cable and a vibration sensor.

SVAN PC++

All measurement files are saved in the internal memory of the instrument, but after this more complex analyses can be carried out using the SvanPC++ Building Acoustics software module. The software includes a very powerful calculator that automatically averages the 1/n octave spectra time history and performs calculation of reverberation time.

BA Assistant

The Building Acoustics Assistant application works on Android platforms, and is easy to install and intuitive to operate. The user interface shows a preview of the results in the form of time-history plots as well as numerical values. The smartphone application helps the user in calculating the insulation in accordance with ISO 16283. Sound insulation results are presented on the display and in the form of a report which is compliant with the ISO requirements. A project containing measurements from the source and receiving rooms for different sound source positions is created during the measurement process. The project is saved in the memory of the sound meter along with the measurement files.
