The science of designing rooms for best sound effects.
A measure of the strength of an electronic signal.
The range of sounds that can be heard by the ear.
Low frequency sound, usually below 300 Hz.
A pattern in musical rhythm caused by 2 tones at different frequencies
(usually close), so that they regularly form highs and lows in loudness.
A musical scale for measuring pitch.
Electrical energy similar to sound waves but caused by electrical
vibrations and traveling through wires.
Electromagnetic energy similar to electrical waves but caused by electrical
vibrations at higher frequencies and traveling through air; used for many
forms of communications.
The rate at which a pattern or wave repeats itself.
The lowest (and usually the loudest) frequency in a tone.
The electronics term for frequencies that are exact multiples of a lower
frequency (the fundamental) produced by the same source.
The number of repetitions per second.
An electronic circuit that has been made very, very small.
The number of repetitions per second, expressed in thousands.
A device which converts electrical energy into light.
A measure of the strength of sound waves, also called volume.
The number of repetitions per second, expressed in millions.
An international system of measurement.
A device which converts sound waves into electrical waves.
A measure of the pitch of a sound, expressed using semitones and
overtones in a musical scale.
Mechanical vibrations (sound waves) occurring in an irregular manner with
their energy spread across a wide range of frequencies, usually annoying
to hear.
The musical term for frequencies that are exact multiples of a lower
frequency (the fundamental) produced by the same source.
Drum-like, hitting one thing against another.
The musical world's term for frequency, expressed using a musical scale;
may be perceived differently between people.
A board for mounting electronics components that has copper traces
"printed" on the surface for connecting the components instead of using
wires.
A fundamental frequency with no overtones.
