  2. Microwave auditory effect - Wikipedia

    en.wikipedia.org/wiki/Microwave_auditory_effect

    The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons ...

  3. Infrasound - Wikipedia

    en.wikipedia.org/wiki/Infrasound

    Infrasound, sometimes referred to as low frequency sound, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard). [ 1] Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be ...

  4. Perception of infrasound - Wikipedia

    en.wikipedia.org/wiki/Perception_of_infrasound

    Infrasound is sound at frequencies lower than the low frequency end of human hearing threshold at 20 Hz. It is known, however, that humans can perceive sounds below this frequency at very high pressure levels. [ 1] Infrasound can come from many natural as well as man-made sources, including weather patterns, topographic features, ocean wave ...

  5. Neural encoding of sound - Wikipedia

    en.wikipedia.org/wiki/Neural_encoding_of_sound

    The neural encoding of sound is the representation of auditory sensation and perception in the nervous system. [ 1] The complexities of contemporary neuroscience are continually redefined. Thus what is known of the auditory system has been continually changing. The encoding of sounds includes the transduction of sound waves into electrical ...

  6. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    Hazards. Dielectric heating from electromagnetic radiation can create a biological hazard. For example, touching or standing around an antenna while a high-power transmitter is in operation can cause burns. The mechanism is the same as that used in a microwave oven.

  7. Psychoacoustics - Wikipedia

    en.wikipedia.org/wiki/Psychoacoustics

    Psychoacoustics. Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system. It is the branch of science studying the psychological responses associated with sound including noise, speech, and music. Psychoacoustics is an interdisciplinary field including psychology ...

  8. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    Auditory system. Anatomical terminology. [ edit on Wikidata] How sounds make their way from the source to the brain. The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system. [ 1]

  9. Cosmic ray visual phenomena - Wikipedia

    en.wikipedia.org/wiki/Cosmic_ray_visual_phenomena

    Cosmic ray visual phenomena, or light flashes ( LF ), also known as Astronaut's Eye, are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. While LF may be the result of actual photons of visible light being sensed by the retina, [1] the LF discussed here ...
