Room Acoustics The room acoustics is concerned with the impact of the structural conditions of a room and sound events held in it. Task of room acoustics, it is primarily to affect the acoustic properties of a room so that the acoustic properties suit well with its intended purpose. The acoustic is of great importance [...]

Building Acoustic The building acoustics deals with sound propagation between rooms within a building respectively from outdoors into the room. The transmission of the sound takes place by emission of airborne noise from the vibrating building structures. Besides the traditional fields airborne sound insulation (sound) and impact sound insulation (sound insulation), the entire area of [...]
