  • HEARING PROTECTION DEVICES
    Publication number: 20240225903
    Abstract: A hearing protection device (500) arranged to provide an acoustic barrier is disclosed. The hearing protection device (500) includes a microphone (502) arranged to measure sound behind the acoustic barrier. The device (500) determines whether a sound level characteristic of the sound measured by the microphone (502) is above a predetermined threshold. When the sound level characteristic measured by the microphone (502) is above the predetermined threshold, the device (500) compares the sound level characteristic of the sound behind and outside the acoustic barrier to determine an attenuation of the device (500). If the determined attenuation is below a cut-off level of attenuation, the device (500) provides an alert.

  • Sound absorbent
    Patent number: 7677359
    Abstract: Sound absorbent (1) of a hard material, such as metal, glass, hard plastic or composites thereof, for absorption of acoustic waves by friction of viscous flow, essentially in the frequency range between 100 and 4000 Hz. The sound absorbent (1) comprises a panel element (3) with microslits (5) therethrough, said microslits (5) having a minimum slit width (b) of less than 0.45 mm. When in use, the panel element (3) is arranged with a distance to a rear surface.
