Laboratory exercise for measuring sound absorption coefficient and transmission loss coefficient
Kovanda, Jindřich ; Balík, Miroslav (referee) ; Skvaril, Šimon (advisor)
This thesis refers about measuring absorbtion coeficient of various materials using impedance tube by transfer function method. This thesis also deals with examinating used impedance tube, designing the adjustments for eliminating its flaws. Also the thesis deals with designing impedance tube for measurements of absorbtion coeficient, transmition coeficient and transmition loss, measuring transmition loss, creating measuring and computing program for this measurement and designing laboratory exercise dealing with this measurement.
The Evaluation of masking of harmonic components in a mixture
Kovanda, Jindřich ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This thesis deals with design and creation of listening test in which its respondents were setting certain harmonic of the tone to mixture of up to 16 harmonics. The respondents were setting intensity of the harmonic to the border position, in which the harmonic was not masked by the other harmonics in the tone and in which the harmonic stood up from the mixture. The respondents were stetting the harmonics from the first to sixteenth, in various types of the spectrum, pitch and intensity of the tone. Based on the results relations were found which determine how the perception of masking of harmonics vary with their order in the spectrum.
