Such a PWPT is designed to match the psychoacoustic model and to improve the performance of speech denoising [11].
According to the company, the tool exploits a psychoacoustic model to maximize the reach and intelligibility of AM transmissions while lowering distortion and reducing listening fatigue.
They also explored other methods focused on masking the musical noise using psychoacoustic models [6]; results obtained by using these algorithms show that there is a need for further improvement in the radar speech enhancement algorithm, especially at a very low SNR condition (SNR < 10 dB).
