Acoustic chamber and equipment for measuring noise level Theseus Lab

The acoustic chamber and measuring equipment allow to measure sound level from various equipment, including household, industrial, as well as special purpose equipment.

The workstation consists of a set of high-precision microphones, a multichannel signal level meter, a calibrator, a set of tripods for microphones fixing, an acoustic chamber and specialized software.

The chamber has a metal prefabricated panel structure. In order to assemble the panels, they should be transported into the room and mounted.

Panels are a fabricated block, made of special sound-absorbing material.

Design of the chamber allows mounting water conduit, sewage, and various telecommunications interfaces for testing a wide range of products.

The chamber is equipped with a ventilation system and a double-leaf door.

Special software allows to measure sound and noise levels, as well as perform vibration measurements.

Equipment can record signals with duration of several hours in real-time mode. The equipment has octave filters for filtering in accordance with the requirements of technical regulations.

Workstation fully meets the requirements of ANSI S1.4 and IEC 61672 for the equipment of class 1.

The equipment allows to measure sound intensity and the index of the intensity of residual sound pressure in real time mode, using standard microphones.

The sound power is an absolute measure for determining the noise produced by the equipment. All devices from PC fans to heavy equipment must meet the requirements of existing standards. This workstation completely copes with these tasks.
