"Wine glass" pulpit and sounding board at St. Matthew's German Evangelical Lutheran Church in Charleston, SC. A sounding board, also known as a tester and abat-voix is a structure placed above and sometimes also behind a pulpit or other speaking platform that helps to project the sound of the speaker. It is usually made of wood.
Through this process, an alternating series of compression and rarefaction pulses travel away from the soundboard, creating sound waves. [5] The soundboard operates by the principle of forced vibration. The string gently vibrates the board, and despite their differences in size and composition, makes the board vibrate at exactly the same frequency.

An acoustic board is a board made from sound absorbing materials, designed to provide sound insulation. [3] [4] Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is balanced by producing heat energy.
For the line source to work, the drivers in each passband need to be in a line. Therefore, each enclosure must be designed to rig together closely to form columns composed of high-, mid- and low-frequency speaker drivers. Increasing the number of drivers in each enclosure increases the frequency range and maximum sound pressure level, while ...

Sound engineers take several steps to maximize gain before feedback, including keeping microphones at a distance from speakers, ensuring that directional microphones are not pointed towards speakers, keeping the onstage volume levels down, and lowering gain levels at frequencies where the feedback is occurring, using a graphic equalizer, a ...
