Conclusions

The acoustical properties of heat-bonded and needle-punched fibrous materials have been studied by the steady-state method.

The basic structural and technological parameters which affect the sound-absorption coefficient of these materials have been established.

It has been shown that heat-bonded fibrous materials have advantages over the needle-punched ones, since they ensure an equal sound-absorption coefficient at a lower thickness.
