Noise spectra for calculation the speech transmission index in public address systems

Autor: Paweł Dziechciński

Publikováno v: International Journal of Electronics and Telecommunications, Vol vol. 70, Iss No 3, Pp 555-562 (2024)

To precision calculate the speech transmission index (STI), it is necessary to know the level and spectrum of the interfering noise. Simplified design methods used in public address systems are limited to obtaining an appropriate signal-to-noise rati

Crowd noise spectra for the calculation of the speech transmission index for public address systems

Autor: Paweł Dziechciński

Publikováno v: International Journal of Electronics and Telecommunications, Vol vol. 70, Iss No 3, Pp 609-614 (2024)

Knowledge of interfering noise is necessary for the correct design of a public address system. Noise sound levels can be obtained, for example, from BS 5389-1. It is more difficult to acquire knowledge of the interfering noise spectra, and the spectr

Effect of Power Amplifier Distortion on the Speech Transmission Index for Public Address Systems

Autor: Paweł Dziechciński

Publikováno v: Archives of Acoustics, Vol vol. 47, Iss No 2, Pp 191-199 (2022)

The effect of the power amplifier on speech intelligibility in public address systems is often marginalised – i.e. it is assumed that it does not introduce significant signal distortion. This approach is justified when the linear range of the ampli
