View at: Publisher Site Google Scholar Acoustic transmission in building design refers to a number of processes by which sound can be transferred from one part of a building to another. Typically these are: Airborne transmission - a noise source in one room sends air pressure waves which induce vibration to one side of a wall or element of structure … See more Acoustic transmission is the transmission of sounds through and between materials, including air, wall, and musical instruments. The degree to which sound is transferred between two … See more Musical instruments are generally designed to radiate sound effectively. A high-impedance part of the instrument, such as a string, transmits vibrations through a bridge (intermediate impedance) to a sound board (lower impedance). The soundboard then … See more Stethoscopes roughly match the acoustical impedance of the human body, so they transmit sounds from a patient's chest to the doctor's ear … See more • Acoustic absorption • Acoustic attenuation • Architectural acoustics • Attenuation coefficient See more
