Hearing

52.0K
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.

Perceiving Loudness, Pitch, and Location

205
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

4.4K
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...

The Cochlea01:13

The Cochlea

44.7K
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.

Classification of Signals01:30

Classification of Signals

437
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...

Area of Science:

  • Audiology
  • Artificial Intelligence
  • Machine Learning

Background:

  • Tonal audiometry is standard for diagnosing hearing loss, but interpretation requires specialists, leading to diagnostic delays.
  • Limited availability of audiologists impacts timely diagnosis and treatment of hearing impairments.

Purpose of the Study:

  • To develop and evaluate a neural network for automated classification of tonal audiometry data.
  • To classify hearing loss into four categories: normal, conductive, mixed, and sensorineural.

Main Methods:

  • Utilized a Bidirectional Long Short-Term Memory (BiLSTM) neural network architecture.
  • Trained the model on 15,046 audiometry results analyzed and categorized by professional audiologists.

Main Results:

  • Achieved 99.33% classification accuracy on an independent dataset.
  • The model effectively distinguishes between normal hearing and different types of hearing loss.

Conclusions:

  • The AI model offers a reliable method for classifying tonal audiometry results, potentially reducing diagnostic burdens.
  • Enables general practitioners to classify results for referrals and supports audiologists/otolaryngologists as a decision support tool.
