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 ...
The ultrasound within tissue consists of very high frequency sound waves, between 800,000 Hz and 20,000,000 Hz, which cannot be heard by humans. Some of the advantages of ultrasound as a diagnostic and therapeutic tool include its safety profile, lack of radiation, portability, and low cost. [ 4 ]
High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth.It commonly refers to 96 or 192 kHz sample rates.
The brown note (sometimes brown tone or frequency), is a hypothetical infrasonic frequency capable of causing fecal incontinence by creating acoustic resonance in the human bowel. Considered an urban myth , the name is a metonym for the common color of human faeces .

A PCM signal is a sequence of digital audio samples containing the data providing the necessary information to reconstruct the original analog signal.Each sample represents the amplitude of the signal at a specific point in time, and the samples are uniformly spaced in time.
This does not mean that frequencies above 100 kHz are audible, but that time discrimination is not directly coupled with frequency range. [7] [8] Frequency resolution of the ear is about 3.6 Hz within the octave of 1000–2000 Hz That is, changes in pitch larger than 3.6 Hz can be perceived in a clinical setting. [6]
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.
