Abstract
A device for absorbing and/or damping sound waves has a system for damping and/or silencing sound waves provided with a thin vibratory layer (1) on the side facing the sound waves. In order to improve sound damping and silencing properties, even during a prolonged use with concomitant exposure to strong heat, the thin vibratory layer (1) is made of aluminum or an aluminum alloy and is 0.004 to 0.35 mm thick.
Claims36
A sound wave absorbing and/or attenuating system comprising:
- a system of resonance chambers (2) for the sound waves;
- and a thin vibratable layer (1) of aluminum or an aluminum alloy covering the system of resonance chambers (2), the vibratable layer (1) having a thickness ranging between 0.004 and 0.35 mm on the side facing the incident sound waves.
A sound wave absorbing and/or attenuating system comprising a resonance chamber (2) for the sound waves having at least one surface defined by a thin vibratable layer (1) of aluminum or an aluminum alloy having a thickness ranging between 0.004 and 0.35 mm on the side facing the incident sound waves.
A device for absorbing and/or attenuating sound waves with a sound wave absorbing and/or attenuating system using a thin vibratable layer on the side facing the incident sound waves, wherein the thin vibratable aluminum layer (1) is made of aluminum or an aluminum alloy and has a layer thickness ranging from 0.004 to 0.35 mm.
