Binary amplitude sequences can represent reflection and absorption in diffuser design
Evidence
The most obvious sequences to consider are binary, that is, they contain only levels 0 and 1, where 1 represents reflection from a hard surface and 0 represents absorption from some form of absorbing material. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 2103
