Anechoic Chambers

DNV Industries offer you one of the high quality products of their company which is known as Anechoic Chambers. All of our products are ISO-9001 2008 and fulfills all the norms of the environment. We are one of the leading manufacturers of Anechoic Chambers in India. We are also specialist in designing of Anechoic and Semi-Anechoic test rooms and chambers. The main use of these anechoic chambers is that these are commonly used to perform experiments in nominally free field conditions. In these anechoic chambers sound energy reduces and travels away from the source with almost none being reflected back. The main and common work of these anechoic chambers is that these chambers measure the transfer function of a loudspeaker or the directivity of noise radiation from industrial machinery. We, DNV Industries make use of sophisticated technology for manufacturing these anechoic chambers and ensure that these offer complete satisfaction to our clients.

Anechoic Test Box

Anechoic Boxes are those boxes which provide a compact, low-cost test environment. This environment is essential for manufacturers of small devices and components so that they can measure, accurately, the noise emissions of their products. These anechoic boxes are useful to test communication equipments, precision instruments, electronic products, nanotechnology - related products, and environmental related products. Anechoic boxes are ideally used to two purposes. One is to produce an exact acoustic replicate of an electric input signal and second is to exclude all external noise. You can easily use these anechoic test boxes on your desk in a unit that is so small.

These anechoic test boxes are the excellent solutions for external noise, even at low frequencies and well defined uniform test conditions. These are also used for obtaining accurate and repeatable measurements. These anechoic test boxes are designed in rectangular shapes. Table top design of these anechoic test boxes consist of the main bottom section that contain the sound source and the measuring plane. The main use of these anechoic test boxes is that these are used for fast and reliable testing of hearing aids and microphones in a uniform sound field. These anechoic test boxes are also used for investigation of hearing aids, microphones, earphones and telecoils.

There are several unique features of these anechoic test boxes like these are high insulation against airborne noise with wide frequency range. These products uniform sound field across the measurement plane and usable for pressure microphones down and have handy table-top design.

Reverberation Rooms

Reverberation Rooms are designed and built for the determination of sound power output of noise sources. Some more uses of these reverberation rooms are transmission loss of partitions, insertion loss of silencers, response characteristics of microphones, and random incidence absorption coefficients of materials. These reverberation rooms are also designed and used for high-intensity noise-level fatigue testing of aircraft, space vehicles, and other equipment.

DNV Industries is very efficient in making reverberation rooms and these rooms are not only designed to fully satisfy reverberation requirements but also meet specific interior acoustic sound levels and other environmental requirements. There are some more things which we specially consider during the design of these reverberation rooms like to provide suitable working spaces, sizes and types of doors, lighting and electrical systems, climate controls, as well as RF shielding appropriate to the work intended. All these elements are assembled within an engineered modular structural framework Reverberation Room.

DNV Industries is the pioneer and leading company in the design, construction, and commissioning of modular reverberation rooms in Noida, India.
