  2. Violin acoustics - Wikipedia

    en.wikipedia.org/wiki/Violin_acoustics

    For vibrations with a large amplitude, the tension is not constant. [28] Increasing the tension on a string results in a higher frequency note: [12] the frequency of the vibrating string, which is directly proportional to the square root of the tension, [3] can be represented by the following equation:

  3. Overtone - Wikipedia

    en.wikipedia.org/wiki/Overtone

    An overtone is a partial (a "partial wave" or "constituent frequency") that can be either a harmonic partial (a harmonic) other than the fundamental, or an inharmonic partial. A harmonic frequency is an integer multiple of the fundamental frequency. An inharmonic frequency is a non-integer multiple of a fundamental frequency.

  4. Audio frequency - Wikipedia

    en.wikipedia.org/wiki/Audio_frequency

    An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.

  5. Amplitude - Wikipedia

    en.wikipedia.org/wiki/Amplitude

    Peak-to-peak amplitude (abbreviated p–p or PtP or PtoP) is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope .

  6. Ohm's acoustic law - Wikipedia

    en.wikipedia.org/wiki/Ohm's_acoustic_law

    The law has also been interpreted as "a pitch corresponding to a certain frequency can only be heard if the acoustical wave contains power at that frequency." [7] These laws are true to the extent that the ear is sensitive to the frequency and amplitude of the acoustic waves, and further, is able to resolve the differences in their frequency.

  7. Harmonic series (music) - Wikipedia

    en.wikipedia.org/wiki/Harmonic_series_(music)

    A "complex tone" (the sound of a note with a timbre particular to the instrument playing the note) "can be described as a combination of many simple periodic waves (i.e., sine waves) or partials, each with its own frequency of vibration, amplitude, and phase". [1] (See also, Fourier analysis.)

  8. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties: Frequency, or its inverse, wavelength; Amplitude, sound pressure or Intensity; Speed of sound; Direction; Sound that is perceptible by humans has frequencies from about 20 Hz to 20,000 Hz.

  9. A440 (pitch standard) - Wikipedia

    en.wikipedia.org/wiki/A440_(pitch_standard)

    A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
