In psychoacoustics and signal processing, a pure tone is a sound or a signal with a sinusoidal waveform; that is, a sine wave of any frequency, phase-shift, and amplitude. A pure tone has the property – unique among real-valued wave shapes – that its wave shape is unchanged by linear time-invariant systems; … Visa mer Pure tones have been used by 19th century physicists like Georg Ohm and Hermann von Helmholtz to support theories asserting that the ear functions in a way equivalent to a Fourier frequency analysis. … Visa mer • Sound • Pitch (music) • Musical tone • Missing fundamental Visa mer WebbOn the oscilloscope a noise will look like a ragged jumble of ups and downs, usually with sharp peaks and troughs. A pure note will be a smooth wave with no quick changes. The …

Few music enthusiasts would be impressed by an orchestra that played music consisting of the note with a pure tone played by all instruments in the orchestra. Hearing a sound wave of 256 Hz (middle C) would become rather monotonous (both literally and figuratively).
