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.

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...

Assessment of Respiration01:23

Assessment of Respiration

2.3K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Drug Dosing: Geriatric Patients

395
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Auditory Perception01:17

Auditory Perception

1.5K
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...

Aging01:26

Aging

1.1K
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Area of Science:

  • Audiology
  • Gerontology
  • Speech-Language Pathology

Background:

  • Hearing impairment is prevalent in older adults.
  • Standard speech audiometry protocols may require adaptation for this population.
  • The Punch and Rakerd (2019) protocol offers an integrated approach using spondaic words.

Purpose of the Study:

  • To assess the ecological validity of the Punch and Rakerd (2019) speech audiometry protocol.
  • To evaluate the protocol's implementation in older adults with hearing impairment.
  • To examine the clinical acceptability and participant experience of an automated speech audiometry protocol.

Main Methods:

  • The study involved 12 older adults with sensorineural hearing loss.
  • An integrated speech audiometry protocol was administered, measuring speech recognition threshold (SRT), most comfortable loudness (MCL), and uncomfortable loudness (UCL).
  • Stimulus presentation, response collection, and test timing were automated, followed by a subjective questionnaire.

Main Results:

  • SRT measurements correlated well with pure-tone averages.
  • MCL and UCL values aligned with established data for similar hearing loss.
  • Bilateral testing averaged 13.1 minutes, with highly positive participant feedback.

Conclusions:

  • The automated, integrated speech audiometry protocol is ecologically valid for older adults with sensorineural hearing loss.
  • The protocol produces clinically acceptable results in this demographic.
  • Automated testing enhances efficiency and user experience in audiological assessments.
