an enclosed space for producing reverberation of a sound
Reverberation The first reverb effects created for recordings used a real physical space as a natural echo chamber. A loudspeaker would play the sound, and then a microphone would pick it up again, including the effects of reverb. Although this is still a common technique, it requires a dedicated soundproofed room, and varying the reverb time is difficult.
Larynx The larynx (/ˈlærɪŋks/; plural larynges; from the Greek λάρυγξ lárynx),[1] commonly called the voice box, is an organ in the neck of tetrapods involved in breathing, sound production, and protecting the trachea against food aspiration. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. They are situated just below where the tract of the pharynx splits into the trachea and the esophagus.
