Hearing

52.5K
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.

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

239
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Perception of Sound Waves01:01

Perception of Sound Waves

4.5K
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...

Auditory Perception01:17

Auditory Perception

364
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Area of Science:

  • Audiology and Hearing Healthcare Innovation
  • Health Services Research

Background:

  • The hearing healthcare industry is undergoing rapid evolution, necessitating better tools for understanding service and product delivery.
  • Current audiological care lacks a framework to match individual needs with available provision options.

Purpose of the Study:

  • To develop a framework for describing and discussing service and product delivery options in contemporary hearing care.
  • To provide a structured approach for clinicians and clients to navigate hearing healthcare solutions.

Main Methods:

  • A systematic review using the PRISMA approach.
  • Mapping, validation, and thematic analysis of relevant literature and validation criteria.

Main Results:

  • No existing frameworks were identified for matching needs with current hearing care provision options.
  • A novel framework was developed with three core domains: Service, Channel, and Technology/Device.
  • The framework differentiates innovation in technology, service delivery, and the channels used.

Conclusions:

  • The developed framework enhances understanding of innovation within the hearing healthcare industry.
  • It allows for disambiguation of hearing health services, hearing loss technology, and delivery channels.
  • The framework has potential as a versatile tool for the hearing healthcare sector.
