Speech intelligibility metrics can be predicted from impulse response and noise

Evidence

The MTF can, in principle, be measured with signals that have energy at all audible frequencies and modulations at all modulation frequencies of interest. Speech, music, and other such signals can be used. However, the measurement can be conducted with more accuracy using signals specifically designed for the task. The MTF can also be estimated during the design of the acoustics of halls, or during the design of public address systems, if the impulse response and background noise levels can be estimated. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2415
