Scientific pitch, also known as philosophical pitch, Sauveur pitch or Verdi tuning, is an absolute concert pitch standard which is based on middle C (C 4) being set to 256 Hz rather than approximately 261.63 Hz, [1] making it approximately 31.77 cents lower than the common A440 pitch standard.
Diagram of beat frequency. In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized.
Human mechanoreceptors, such as Pacinian corpuscles, can detect vibrations up to 1,000 Hz, frequencies between 30 Hz and 120 Hz are generally considered to have a calming and relaxing effect, which is why they are often used in therapeutic contexts.40 Hz specifically, has been widely studied in vibroacoustic therapy and other fields due to its ...
Music therapy may be suggested for adolescent populations to help manage disorders usually diagnosed in adolescence, such as mood/anxiety disorders and eating disorders, or inappropriate behaviors, including suicide attempts, withdrawal from family, social isolation from peers, aggression, running away, and substance abuse.
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.

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.
The sounds produced by bottlenose dolphins are lower in frequency and range typically between 75 and 150,000 Hz. The higher frequencies in this range are also used for echolocation and the lower frequencies are commonly associated with social interaction as the signals travel much farther distances.
