Sound

Sound is a mechanical wave an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations. Sound is a sequence of waves of pressure which propagates through […]

For frequencies below 300 Hz there is a noticeable range of difference between the trends of the absorption coefficients of MDF and fiber cement. Above this frequency, similarities of these trends can be observed not including the region where that of the MDF peaks. It is also evident from the graph that the absorption coefficient […]
