Echoloze meetbox voor het testen van oormicrofoons of kleine geluidbronnen

Aurolex heeft in haar programma de BSWA echo loze meetbox voor het verrichten van geluidmetingen aan kleine geluidbronnen zoals oorluidsprekers. De echoloze mini meetkamer kan ook gebruikt worden voor het door meten en testen van microfoons. De echo loze meetbox wordt voor het verrichten van oor-luidsprekers gebruikt in combinatie met een kunstoor volgens de IEC-711 richtlijn. Hieronder vindt u meer informatie in het engels.

ABox260 is a small anechoic box fitted with modified Type 3.2 simplified pinna simulator. It uses IEC711 artificial ear coupler for testing ear-speakers in the factory environments.  ABox260 meets the ITU-T Rec. P.57 Artificial Ear Type 3.2 high-leak requirements.
The box is made of aluminum plate. The internal surface is fitted with BASOTECT sound absorption material. Type 3.2 simulator is fitted on top of the box. The Device Under Test (DUT) can be installed on simulator via the application adaptor.
To reduce the environmental noise, a silencer is specially designed. A linear bearing was used to move the silencer vertically. The DUT will be inside the silencer during the testing.
The pin-connectors are integrated with the silencer. When the silencer is pressed down, the pins will connect to the DUT to perform the testing. The pins also provide the 5-10 N force to the DUT.

FEATURES

  1. According to ITU-T Recommendation. P.57 “Artificial Ear” (11/2005) Type 3.2 with high-leak simplified pinna simulator.
  2. Specially designed anechoic box for artificial ear.
  3. Specially designed silencer to reduce factory noise influence.

APPLICATIONS

  1. High volume ear-speaker testing based on Type 3.2 high leak ear in factory environments.
  2. Other product testing which requires Type 3.2 high leak ear

Acoustical Input Impedance
ITU-T P.57 specified the acoustic input impedance of Type3.2 high leak ear. Each box was tested for the impedance and the typical results are shown in Figure 1
