Acoustic Test & Measurement Chamber
Trishul can design and manufacture engineered acoustical test chambers that will either isolate the test chamber from the ambient providing a specific, controlled interior acoustical environment in which to perform accurate & repeatable testing; or to enclose the test and contain and isolate high sound levels generated by the test from reaching the ambient.
The design method and materials of construction will depend largely upon the performance criteria specified for any given project. The most common project will be shipped as modular components & assembled on site. Trishul also provides factory pre-assembled chambers that are portable robust structures complete with isolated floors when required.
Most typical applications can be designed around a version of our modular acoustical panel range as the basis of construction featuring a wide range of performance in a single wall chamber design. For those applications specifying more stringent performance criteria, we can enhance the panel construction to achieve greater performance, utilize a double-wall chamber design or a combination of thereof.
Trishul can design and manufacture engineered test chambers that will provide a specific, controlled acoustical environment in which to perform accurate and repeatable testing of many types. From a table top chamber to a small vehicle test cell, we will custom design a system specifically for your testing criteria. Our acoustical test chambers provide high sound isolation from ambient environment, low interior sound level, with reverberation or anechoic characteristics. We design acoustical test chambers for the automotive, energy, telecommunications, aerospace and consumer products industries as well as for use by universities, OEM's and government clients.
Using our high STC rated modular acoustical metal panels to construct the superstructure and tuned anechoic wedges to line the interior, we can design systems to provide interior sound levels less than 35dBA with low frequency cut off from 80 Hz to 250 Hz. We offer a variety of accessories such as automatic sliding parts doors, integrated ventilation systems, data entry sleeves, interior lighting, etc., to meet your project requirements.
