Audio Precision Supports New Loudspeaker Test Standard

BEAVERTON, Ore., March 24, 2015 /PRNewswire/ -- Audio Precision, the recognized standard in audio test, today announced the availability of an application that facilitates the testing of small loudspeakers per requirements established by the Republic of Korea's Telecommunications Technology Association (TTA). Founded in 1998, TTA is a non-governmental, non-profit organization dedicated to standardization, testing, and certification services for the information technology and communications industries in South Korea.

This application, referred to as the APx TTA Loudspeaker Test Utility, uses the Application Programming Interface (API) of AP's popular APx audio test software to control and interact with an APx500 Series audio analyzer to verify the performance of micro and slim speakers relative to TTA's standard number TCB-0054(00) – "TTA Verified Testing Criteria for Micro/Slim Speakers." Tests performed by the utility include: Effective Frequency Range (EFR), Distortion and Sensitivity, Maximum Sound Pressure Level (SPL), and Impedance. The utility is compatible with APx500 Series audio analyzers, except the APx511, and requires software option SPK-RD, an IMP1 Impedance Fixture, a power amplifier, and a suitable measurement microphone.  

"As I worked to develop Korea's criteria for testing micro-speakers, collaborating with the market leader in audio test was a natural choice," said Sin-Lyul Lee, Ph.D., Technical Adviser, Next-generation Sound Support Center (NSSC). "Needless to say, Audio Precision's dedicated and thorough approach to creating the TTA loudspeaker test utility is greatly appreciated."

"From fundamental audio testing to compliance testing for global, regional and national standards, our ultimate goal is to help engineers bring their products to market," stated Dave Schmoldt, Audio Precision CEO. "Providing this utility in support of TTA's micro/slim speaker standard is one more example of the AP team's focused efforts toward achieving that goal."

The APx TTA Loudspeaker Test Utility is available now for download by registered users of AP.com.
