A sound spectrum is a representation of a sound – usually a short sample of a sound – in terms of the amount of vibration at each individual frequency. It is usually presented as a graph of …

So C4 on the flute contains some vibration at C4 (let's call its frequency f o), some at C5 (2f o), some at G5 (3f o), some at C6 (4f o), etc. The 'recipe' of the sound in terms of its component …

So, to summarise, the spectrum of the output sound depends on the spectrum of the laryngeal source, on the frequency-dependent ‘gain’ of the vocal tract, including how well the sound is …

The 'recipe' of the sound in terms of its component frequencies is called its sound spectrum. The predominant presence of odd harmonics in the lowest or chalumeau register gives this register …

A more complex sound may be considered as the sum of many sine waves, and the sound spectrum may be thought of as a 'recipe' for creating that sound: each point on the graph of …

The disturbance in the air spreads out as a travelling sound wave. Ultimately this sound wave causes a very tiny vibration in your eardrum. At any point in the air near the source of sound, …

The harmonic series of notes is explained in terms of the standing waves of the instrument on the page Pipes and harmonics. This page also explains why sound spectra of notes in the low …

A nearly linear relation gives rise to nearly sinusoidal vibration (i.e. one shaped like a sine wave), which means that the fundamental in the sound spectrum is strong, but that the higher …

It is a spectrum, because it has different values for different frequencies. When we measure it at the mouthpiece of an instrument, it tells us a lot about the way the player's lips, reed or the air …

The frequency response of the vocal tract is quantified by its acoustic impedance spectrum, a measure of how difficult it is to produce vibration at a given frequency. Our key technical …
