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...

Hearing01:31

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.

Classification of Signals01:30

Classification of Signals

519
In signal processing, signals are classified based on various characteristics: continuous-time versus discrete-time, periodic versus aperiodic, analog versus digital, and causal versus noncausal. Each category highlights distinct properties crucial for understanding and manipulating signals.
A continuous-time signal holds a value at every instant in time, representing information seamlessly. In contrast, a discrete-time signal holds values only at specific moments, often denoted as x(n), where...

Sound Intensity Level00:53

Sound Intensity Level

4.2K
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

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...

Difference from Background: Limit of Detection01:05

Difference from Background: Limit of Detection

6.4K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Area of Science:

  • Audiology
  • Biomedical Engineering
  • Public Health

Background:

  • Hearing loss affects a significant portion of the population, yet hearing aid acceptance is low, partly due to fitting issues.
  • Traditional hearing assessments require travel to specialized clinics, posing a barrier for rural populations.
  • Over-the-counter (OTC) hearing aids offer a potential solution, but require effective remote fitting methods.

Purpose of the Study:

  • To investigate the efficacy of patient-controlled hearing assessments using a hearing aid in a non-clinical setting.
  • To determine if remote hearing assessments can reliably substitute traditional, in-clinic audiological evaluations.
  • To assess the accuracy of hearing measurements obtained via a hearing aid compared to standard audiometry.

Main Methods:

  • A hearing aid was utilized for patient-controlled hearing assessments in a non-clinical environment.
  • Measurements were compared against standard, audiologist-controlled hearing assessments conducted in a clinical setting.
  • The accuracy of the hearing aid measurements was evaluated against established audiological procedures and Gaussian Process modeling.

Main Results:

  • Patient-controlled hearing assessments were not statistically different from audiologist-controlled assessments.
  • The hearing differences measured by the study's device were within 3 dB of the standard audiogram results.
  • A slight, uncompensated reduction in sound level was observed at 250 Hz with the hearing aid's sound delivery.

Conclusions:

  • Remote, patient-controlled hearing assessments using hearing aids are a viable alternative to traditional clinical tests.
  • This approach has the potential to improve hearing aid fitting and accessibility, particularly for underserved populations.
  • Further refinement may be needed to address specific frequency responses, such as at 250 Hz.
