  2. Sensory systems in fish - Wikipedia

    en.wikipedia.org/wiki/Sensory_systems_in_fish

    Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders. Hearing is well-developed in carp, which have the Weberian organ, three specialized vertebral processes that transfer vibrations in the swim bladder to the inner ear.

  3. Ultrasonic hearing - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_hearing

    Ultrasonic hearing is a recognised auditory effect which allows humans to perceive sounds of a much higher frequency than would ordinarily be audible using the inner ear, usually by stimulation of the base of the cochlea through bone conduction. Normal human hearing is recognised as having an upper bound of 15–28 kHz, [1] depending on the person.

  4. 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 ...

  5. Hearing - Wikipedia

    en.wikipedia.org/wiki/Hearing

    Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [1] The academic field concerned with hearing is auditory science . Sound may be heard through solid, liquid, or gaseous matter. [2]

    Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma. Tinnitus. Tinnitus is an auditory disorder characterized by the perception of a sound (ringing, chirping, buzzing, etc.) in the ear in the absence of an external sound source. There are two types ...

    The observed vibrations were then converted into sound and the frequency was sped up so the noise would be audible to human ears. Listen to the ear-shattering noise in the video above, and feel ...

  8. Acoustic reflex - Wikipedia

    en.wikipedia.org/wiki/Acoustic_reflex

    The acoustic reflex threshold (ART) is the sound pressure level (SPL) from which a sound stimulus with a given frequency will trigger the acoustic reflex. The ART is a function of sound pressure level and frequency. People with normal hearing have an acoustic reflex threshold (ART) around 70–100 dB SPL. People with conductive hearing loss (i ...

  9. Conductive hearing loss - Wikipedia

    en.wikipedia.org/wiki/Conductive_hearing_loss

    Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear ( ossicles ). If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.
