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.
Isochronic tones can quantitatively be distinguished by both the frequency or pitch of the tone itself, and by the interval or frequency of repetition of the tone. While listening to isochronic tones is a technique often employed in the theoretical practice of brainwave entrainment, there is no significant research that confirms any claims of ...
Only recently has the FFR been evaluated for encoding complex sound and binaural processing. [ 14 ] [ 15 ] [ 16 ] There may be uses for the information the FFR can provide regarding steady state, time-variant, and speech signals for better understanding of individuals with hearing loss and its effects and of people with psychopathology.
A typical binaural recording unit has two high-fidelity microphones mounted in a dummy head, inset in ear-shaped molds to fully capture all of the audio frequency adjustments (known as head-related transfer functions (HRTFs) in the psychoacoustic research community) that happen naturally as sound wraps around the human head and is "shaped" by ...
A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 30 and 100 Hz, the 40 Hz point being of particular interest. [1] Gamma waves with frequencies between 30 and 70 hertz may be classified as low gamma , and those between 70 and 150 hertz as high gamma .
In episode 5 of the sketch show Astronomy Club: The Sketch Show, there is a sketch about an ASMR award show. In season 7, episode 8 ("The Takeback") of the sitcom Brooklyn Nine-Nine, Jake Peralta pretends to be an excessively soft-spoken and famous ASMRtist, helping pull off a reverse heist to put back stolen gems.

Binaural localization, however, was possible with lower frequencies. This is likely due to the pinna being small enough to only interact with sound waves of high frequency. [ 19 ] It seems that people can only accurately localize the elevation of sounds that are complex and include frequencies above 7,000 Hz, and a pinna must be present.
This is a list of 99% Invisible podcast episodes, hosted by Roman Mars. From its inception in 2010 until April 2021, 99% Invisible was produced and distributed by Radiotopia . In April 2021, the company that produces the show (99% Invisible Inc.) was acquired by SiriusXM , with 99% Invisible moving to the Stitcher Radio network.
