Hearing01:31

Hearing

48.0K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

The Cochlea01:13

The Cochlea

41.0K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Assessing Body Temperature - Tympanic membrane

1.4K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Design Example01:23

Design Example

698
The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

Perception of Sound Waves01:01

Perception of Sound Waves

4.7K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

    Area of Science:

    • Audiology
    • Speech and Hearing Science
    • Mobile Health Technology

    Background:

    • Traditional pure-tone audiometry is time-consuming and requires specialized equipment.
    • Phonemes offer a potential alternative for hearing assessment due to their complex acoustic properties.
    • Developing accessible, self-administered hearing tests is crucial for early detection and management of hearing loss.

    Purpose of the Study:

    • To propose and validate a novel smartphone-based hearing assessment method using Korean phonemes.
    • To evaluate the reliability and accuracy of phoneme-based hearing threshold estimation compared to conventional pure-tone audiometry.
    • To assess the potential of this method in reducing testing time for hearing-impaired individuals.

    Main Methods:

    • Developed a smartphone application utilizing four Korean phonemes (/a/, /i/, /sh/, /s/) for hearing assessment.
    • Conducted tests on 15 subjects with mild to severe hearing loss.
    • Employed regression analysis to estimate conventional pure-tone hearing thresholds from phoneme hearing thresholds.

    Main Results:

    • The phoneme-based self-hearing assessment demonstrated high reliability in estimating hearing thresholds for hearing-impaired subjects.
    • The average difference between conventional and phoneme-based thresholds was 5.6 dB HL.
    • The proposed method significantly reduced the mean test time compared to traditional pure-tone audiometry.

    Conclusions:

    • Smartphone-based phoneme audiometry is a reliable and efficient tool for self-hearing assessment.
    • This method offers a practical and time-saving alternative for evaluating hearing thresholds in individuals with hearing impairment.
    • The findings support the integration of mobile health technologies in audiological assessments.
