Testing chambers from IAC Acoustics contain the best possible configuration of our products from many different applications, often resulting in solutions that exceed our clients’ expectations.

Our testing chambers are a showcase of our true capabilities and are often tailored to the individual needs of our clients. With some of the largest, quietest, and best performing chambers, rooms, and pens across the globe, IAC Acoustics is the best possible partner for any kind of testing facility.

Whether it be solving a ground running noise issue at an airport, or pinpointing the noise from a generator, our expertise will help you achieve the best possible results.

 FULLY ANECHOIC CHAMBERS

The IAC Acoustics Microdyne® Schedule 60 anechoic room is designed for the research physicist or engineer who must make precise sound measurements in a free-field acoustic environment. Schedule 60 rooms provide high sound transmission loss (TL) characteristics and have a completely anechoic wedge lined interior to meet these requirements. For maximum sound isolation, these rooms are designed as a room within a room set on a vibration isolation system created for the specific weight and frequency cut-off of the room.

Schedule 40 chambers, on the other hand, are designed for applications and locations where the noise reduction characteristics for a single wall and ceiling construction provide adequate noise isolation. As a result, the Schedule 40 chamber is smaller in overall outside dimensions. In every other respect, the Schedule 40 is similar to the Schedule 60 series with the same standard features and options available.

 STANDAR FEATURES

Microdyne® anechoic rooms come with the following standard features:

• Anechoic wedges (foam, fiberglass or IAC Metadyne®) with the required low-frequency cut-offs
• Double or single wall and ceiling construction
• IAC Acoustics standard ventilation system coupled to the building supply
• Lighting (interior) minimally acoustically reflective
• Tubular cable ports
• Interior non-reflective cable floor system above the floor wedges with a nylon catch net below
• IAC Acousti-flote™ floor system with vibration isolators
• One IAC Noise-lock® wedge acoustic door

  CABLE FLOORS

IAC Acoustics fully anechoic chambers are typically provided with a tensioned cable floor, situated approximately 100mm above the tips of the floor wedges. Beneath this cable floor is a nylon catch net to prevent debris and small objects falling out of reach.

The cable floor consists of stainless steel cable interwoven in a crisscross matrix of 50mm separation. Each cable is tensioned from an acoustically lagged steel ring beam by turnbuckles at one end and a coil spring at the other. This ensures that the floor is strong with even deformation and spring characteristics.

HEMI-ANECHOIC CHAMBERS

IAC Acoustics’ range of single and double wall construction rooms allow for high precision measurements to be carried out in a hemi-anechoic environment. Typical uses include testing microphones, hearing protection devices and hi-fi equipment. The hard, or non-acoustically absorbent floor is typically used when larger, heavier items are to be tested where a fully anechoic facility would be impractical, or when the normal mode of operation is over a reflective plane such as a floor or hard road surface.

High precision hemi-anechoic chambers from IAC Acoustics offer the same build specification as our range of fully anechoic chambers, except with a hard, isolated floating floor, rather than one lined with anechoic wedges.

 REVERBERATION CHAMBERS

A reverberation room can be considered the opposite of an anechoic chamber because its boundaries reflect, rather than absorb sound energy. Reverberation rooms are designed for the determination of sound power output of noise sources, transmission loss of partitions, insertion loss of silencers, response characteristics of microphones and random incidence absorption coefficients of materials. They are also used for high-intensity noise level fatigue testing of aircraft, space vehicles and other equipment.

The purpose of a reverberation room is to create a highly diffused acoustic measurement environment, defined as a sound field in which acoustic energy flows equally in all directions.

A reverberation room must provide sound isolation against extraneous noises and an environment which can be temperature, pressure and humidity controlled.
