PRESS RELEASE NEW HEMI-ANECHOIC TEST CHAMBER FOR GENERAL DOMESTIC APPLIANCES

A new metal wedge hemi-anechoic chamber, designed and manufactured by Eckel Noise Control Technologies using their new SupersoftTM acoustic wedges, has been supplied to the Blythe Bridge facility of General Domestic Appliances (GDA). The chamber is used to test white goods from GDA's Hotpoint, Creda and Cannon ranges. Measuring internally 5.8m x 5.8m x 3.2m high the chamber has an internal ambient measured sound pressure level (Lp) of 18dB(A) and conforms to ISO 3745.

Eckel's SupersoftTM wedges have a perforated metal profile while the acoustic absorptive material within the wedge is encapsulated in an acoustically transparent non-woven fabric, which is chemically resistant and has a Class One fire rating. This eliminates fibre migration from the wedge without reducing its acoustical performance. Having a metal profile makes the SupersoftTM wedges robust and hard wearing, ideal for every day use.

The structure was built using high performance modular acoustic panels with a modular floating floor designed for 5Hz of vibration isolation. The inner ceiling and walls are lined with metal SupersoftTM wedges finish painted in white. An additional independently isolated inertia block was installed for test products to be positioned upon to eliminate vibration into the host structure. Access into the chamber is via a double leaf acoustic door.

Eckel also supplied and installed all the ventilation, power, lighting and plumbing amounting to a true 'turnkey' installation. Because the chamber is constructed from modular components it can be relocated or expanded as required with relative ease. Richard Hellon, GDA's Laboratory Manager, commented: 'The potential disruption that an installation of this kind could cause was kept to a minimum - within eight weeks of Eckel arriving on site I had the keys to a high performance test chamber that had been finished on time and within budget. The chamber is now in daily use as a benchmark tool'. - ends -
