Hill Acoustics licenses LTC to Spectral Measurement

The former test and measurement division of Prism Sound, Spectral Measurement, has agreed a licensing deal with Hill Acoustics to manufacture and sell the company’s Loudspeaker Test Chambers. The Hill Acoustics LTC range comprises a range of Tetrahedral Test Chambers (TTCs), as well as other geometries, that provide test and measurement solutions for loudspeaker cabinets. The benefits of Spectral Measurement’s new LTC range are said to be improved repeatability of measurements and calibrated low-frequency free field response – without the need for large anechoic chambers. The range is also compatible with Spectral Measurement’s existing portfolio of audio test and measurement products, which include dScope Series III and dScope-M1.

Noting that loudspeaker measurement has traditionally been difficult due to the requirement for a very large space to avoid room-related artefacts and the need for the device to be precisely located under test and measurement microphones, Spectral Measurement managing director, Graham Boswell, explained that: ‘Hill Acoustic’s LTC range neatly and inexpensively solves these problems by providing a precise jig for the speaker and microphone and by calibrating the enclosure so that the equivalent free field response can easily be calculated. As well as being accurate and consistent, this compact, low-cost solution also fits perfectly with our company ethos of delivering useful, workable solutions to the audio test and measurement market.’

‘We are looking forward to bringing the Tetrahedral Test Chambers to a worldwide market,’ added Hill Acoustics CTO, Geoff Hill. ‘This agreement with Spectral Measurement helps to achieve that by combining our individual strengths and capabilities in audio measurement and marketing.’
