Reference Speech-recognition curves for a German monosyllabic test in noise: effects of loudspeaker configuration and room acoustics.

Objective: Measurement of reference speech-recognition curves for a specific speech test in typical clinical testing environments and for different loudspeaker configurations.

Design: Speech-recognition scores were measured at four signal-to-noise ratios for five loudspeaker configurations in two anechoic rooms, and in four audiometric test rooms with low reverberation times.

Study Sample: 240 young participants (aged 18-25 years) without hearing impairment participated in the measurements.
