What does not affect the way sound travels in a room?
The angle of the walls and ceiling

Masking is
when one sound is obscured by others; lower pitches usually dominate higher pitches
frequencies that are integral multiples of the fundamental
the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast
the quality of a sound given by its overtones
Harmonics are
when one sound is obscured by others; lower pitches usually dominate higher pitches
frequencies that are integral multiples of the fundamental
the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast
the quality of a sound given by its overtones
Feedback is
when one sound is obscured by others; lower pitches usually dominate higher pitches
frequencies that are integral multiples of the fundamental
the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast
the quality of a sound given by its overtones
Timbre is
when one sound is obscured by others; lower pitches usually dominate higher pitches
frequencies that are integral multiples of the fundamental
the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast
the quality of a sound given by its overtones
