AES Cincinnati Conducts HD Radio Critical Listening Test
Cincinnati - Oct 3, 2005 - The Cincinnati section of the Audio Engineering Society (AES) in coordination with Sonic Arts and the Corbett Studio, the audio recording and production facility of Cincinnati Public Radio, recently conducted a listening test for cross-compatibility of different surround-sound encoding and decoding systems proposed for HD Radio. The equipment used to encode and decode selected cross-genre audio samples was provided by Neural Audio, Dolby Laboratories and SRS Labs for the tests on Sept. 9 and 10.

The mission of the critical listening test was to objectively determine if any issues with cross-compatibility exist among the represented manufacturer's surround sound encoding/decoding systems. The specific systems under test were the Neural Audio 5225 Upmix and Downmix, Dolby DP563/564 using Dolby Pro Logic II, and SRS Labs Circle Surround Digital encoder and decoders.

To ensure objective results, the test was designed with the help of Dr. Ellyn Sheffield, Department of Psychology-Salisbury University. The test protocols adhered to strict audio testing requirements, including no visual or audio feedback among the participants and varied selection playback order, and was overseen by principals from NPR and the Cincinnati section of the AES. Audio selections were auditioned in calibrated 5.1 mix rooms at Sonic Arts.

Each listening test session lasted from 60 to 90 minutes with participants monitoring 16 music selections encoded as a reference sample, an A sample and a B sample--never knowing which encoder/decoder hardware was used to create them. As part of the test, the participants were asked to note overall satisfaction with the sound quality, audio imaging and sound field placement of each audio sample, as well as the observed difference between the Reference, A and B samples.

Alex Kosiorek from the Corbett Studio said, "The Cincinnati section of the Audio Engineering Society was requested to initiate this test to determine the cross compatibility of various surround sound encode/decode systems for broadcast applications. The results from this test will help further the understanding of the cross compatibility of composite surround sound systems proposed for digital and various analog broadcast methods. The results will also shape future testing if and when that is needed."

Feedback from test participants is being statistically summarized by Sheffield. The results will be be used to shape further research and testing of HD Radio surround.

    Harris Demos DRM for Voice of Vietnam
    Cincinnati and Dong Hoi, Vietnam - Oct 4, 2005 - Harris recently traveled to Vietnam to participate in a three-day DRM consortium held in Dong Hoi, the capital city of the Quang Binh province. Engineers at the Voice of Vietnam (VoV), the radio arm of the country's state broadcaster TNVN, initiated the conference to educate VoV officials and various government advisers for broadcasters about DRM.

    The consortium, held July 28 through July 30, was deemed successful by participants, including the VoV's engineering department. Harris provided a demonstration on the technology by converting an operational DX 200 medium-wave AM transmitter to broadcast at 40kW with the DRM signal. Various presentations, including a DRM overview by the Broadcast Engineering Department for VoV, and a discussion on coverage measurements by VT Communications, accompanied Harris' presentation on transmitter conversion. The DX 200 transmission could be heard 120km to the south using professional receivers and 65km to the north with weaker aerial and receiving devices.
