Anechoic Test Equipment https://www.egplindia.com/anechoic-test-equipment.htm https://www.egplindia.com/anechoic-test-equipment.htm Mon, 03 Jun 2019 00:00:00 +0530 NVH Test Chamber https://www.egplindia.com/nvh-test-chamber.htm https://www.egplindia.com/nvh-test-chamber.htm Mon, 03 Jun 2019 00:00:00 +0530 We focused on applications for acoustics, NVH, and vibration analysis. Our engineers working in these fields measure sound and vibration levels to determine whether the engineering redesign or optimization is necessary to meet customer expectations and requirements. The evaluation of sound and vibration, in terms of their impact on the consumer and the surroundings includes not only the objective measurement of noise and vibration, but also the subjective impact. For example, in the automotive industry, this concept may be applied to interior or exterior noise of a car; in the aerospace industry, engineers may perform in-cabin testing or commercial airline flyovers to test ground level noise rating. Engineering specialties in these fields include : Automotive NVH (noise, vibration, and harshness) - the study of unwanted noise and vibration levels including engine, road, wind, electronic seats, brakes, etc. Noise Mapping - the process of externally mapping noise to a particular device under test for the purpose of identifying the major noise sources and determining engineering redesigns. Structural Dynamics and Monitoring - the process of monitoring the vibration and movement of a particular structure.   Applications for NVH Test Chambers : Recording Music/Band practice Voiceovers Broadcasting Industrial testing Quiet loud machinery Industrial Projects Private Conferences Software Audio Hearing Testing Language studies Karaoke Sound testing Trade Shows Government & Military Fully Automatic Anechoic Chamber https://www.egplindia.com/fully-automatic-anechoic-chamber.htm https://www.egplindia.com/fully-automatic-anechoic-chamber.htm Mon, 03 Jun 2019 00:00:00 +0530 We design, manufacturer and install all types of Anechoic Chambers which precise the specifications for many industries and fit to required applications. Anechoic Chamber is a specific type of room which is completely free from sound reverberation. And any sound projected into the room, at any frequency, is fully absorbed. Anechoic Chamber DesignThese chambers are constructed with noise attenuating outer structures of modular panels and have all interior surfaces lined with PU wedges Foam. This has working floors constructed with grating floor sections to support heavy test specimens above the floor wedges. This is basically designed to suppress the internal sound reflections and used for acoustical measurements. The effectiveness of an anechoic chamber is measured in dB of rejection, which is the ratio of direct sound to reflected sound inside the room. Our designed anechoic chamber provides better than 80dB rejection from 20 kHz down to 80H.Industry Applicationswedesign anechoic chambers for the applications that require precision-level acoustic measurements need to optimize product design and performance of Loudspeakers, Microphones , Cell Phones , Information Technology Equipment , Automobile Components.Applicable Test Standards ISO 3744 ISO 3745 ANSI S12.55 Semi Anechoic Chamber https://www.egplindia.com/semi-automatic-anechoic-chamber.htm https://www.egplindia.com/semi-automatic-anechoic-chamber.htm Mon, 16 Sep 2019 00:00:00 +0530 A room which creates free field conditions but above a reflective plane.Above a certain frequency all sound waves that hit the walls or ceiling of the chamber will be absorbed.This type of chamber is normally used in vehicle testing with a rolling round so that the vehicle may be driven. The semi-anechoic chamber then forms a controlled environment with the surrounding acoustic conditions behaving as a sterile version of the real world. In this way accurate measurements of the sound inside and outside the vehicle can be made under operating conditions. Noise Test Booth https://www.egplindia.com/noise-test-booth.htm https://www.egplindia.com/noise-test-booth.htm Mon, 16 Sep 2019 00:00:00 +0530 We offer on line testing booth to test each & every piece of product.

Anechoic Wedges https://www.egplindia.com/anechoic-wedges.htm https://www.egplindia.com/anechoic-wedges.htm Mon, 03 Jun 2019 00:00:00 +0530 Sound Insulation with acoustic foam offer the perfect blend of technical specifications and eye-pleasing aesthetics. The increased NRC ratings across the board will meet even the strictest audiophile's needs. Whether you're a professional musician creating a sound studio, or simply trying to help control some sonic anomalies in your hall, gym or churchWe offer the complete range of acoustic foam in order to meet your acoustic needs. Order by the pack and/or larger sizes for Note regarding custom cut pieces: We try to provide one seamless piece for your order. However, since this foam is manufactured in pairs, we will sometimes send two pieces of half the size you've orderedAcoustic foam is not fire retardant. Use at your own risk.For total sound blocking it is necessary to control the flow of air into and out of a room. Sheet rock walls, ceilings, and floors should be further insulated with 6mm. Acoustic foam is best applied to your walls and surfaces with a heavy staple gun or our adhesive spray. Remember, most acoustic sheets larger than 82" x 96" will have seams. During the vacuum packing process (for shipping) these seams can open. It is recommended that you purchase a can of foam glue to mend any seams that may have ripped during shipping.Acoustic absorption is the key to this line! Go with our 2" Wedges when you're trying to tame frequencies in smaller areas. These are our most popular seller and work great with most acoustical needs. Our 3" Wedges are better at absorbing low-end frequencies than the 2" version. Medium sized areas will appreciate the acoustic accuracy of the 3" wedges. 4" Wedges are best for larger sized areas with bass control issues. If you need maximum acoustic control and sound accuracy, 4" is the size for you.
