Summary

Speech intelligibility will be evaluated for school age children with hearing loss in a simulated classroom environment, using Phonak hearing aids and receivers and two different microphone transmitters: a Roger Touchscreen mic and a fixed directional microphone.

Detailed description

Speech intelligibility will be evaluated for school age children with hearing loss in a simulated classroom environment, using Phonak hearing aids and receivers and two different microphone transmitters: a Roger Touchscreen mic and a fixed directional microphone. The simulated classroom environment will include a teacher condition, in which speech is presented from a distance in front of the participant, and a small-group condition, in which speech is presented randomly from three different speakers around the participant. Both conditions will have diffuse background noise, and the various SNR (Signal to Noise Ratio) levels will be tested. Subjective preference and fatigue questionnaires will also be collected from the participants after the use of each transmitter.

Conditions

Interventions

TypeNameDescription
DEVICEPhonak Roger TouchScreen MicrophoneTransmitter microphone system operating on the 2.4 GHz band, which allows for low-delay and reliable long-range broadcast to a compatible Roger receiver, designed to be used in educational settings. It features six microphones and adaptive technology in which speech signals are increased when background noise increases to ensure that the speech signal is always above the noise level.
DEVICEPhonak Partner MicWireless microphone that uses Phonak proprietary AirStream technology to connect to Phonak hearing aids. It uses a fixed directional microphone, and is paired to the hearing aids such that the hearing aid microphones are attenuated at a fixed level when the microphone is in use.
