Marcos’s loudspeaker design, which comprises eight phase-shift sources in a line, aims to compensate for the hearing loss of a 70-year-old adult, which is of about 15 dB at 3 kHz. The acoustical radiators send a boosted version of the TV audio towards one location, where a hearing impaired TV listener is present. Other listeners with healthy hearing are placed at positions where they do not listen to the amplification provided by the array. Marcos, who won the 2013 Institute of Acoustics (IOA) Young Person’s Award for Innovation in Acoustical Engineering for his array design, says: “Although line arrays have been studied for many years, the approach previously used to reduce the radiation to the rear of the array – and hence reduce reverberant levels for other listeners – has been to position a second set of loudspeakers at the back of the array to cancel the sound in that...
