Room acoustics act as a second system cascaded after the instrument

Evidence

If we are modeling the effect of an instrument being played in a room, then the output we require is the sound heard by the listener and not the output from the instrument itself. The environment itself acts as a sound modifier, and therefore it too acts as a “system” in terms of the input/system/output model. The input to the model of the environment is the output from the instrument being played. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1059

Categorization

• DEFINE: The environment is treated as a modifier system in series with the instrument, making the heard sound a cascaded output.
• XREF: Connects to the reader’s interest in listening and environmental sound; the room-as-chain mirrors how they think about ordinary acoustic experience. — connects to: Room acoustics act as another system modifying the instrument’s output; The auditory system compensates for room acoustics to recover the original source signal — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1535; The room is itself an acoustic system in the model chain — David Howard, Jamie Angus, coustics and Psychoacoustics, 1083 (+5 more)
