The AC45 doorset provides a reduction in acoustic transfer through the door of 45 dB, a level at which loud speech is just detectable. Commonly used in music, rehearsal rooms and in commercial / industrial applications with similar sound levels. These doors have been tested to BS EN ISO 140-3: 1995.
Robust Doors can offer a level of acoustic attenuation from 22 to 54 dB by varying the infill of the door blade and frames. The higher levels of acoustic performance are achieved with custom manufactured doorsets using four-sided frames and acoustic seals.
