Hearing

Hearing

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.

Anatomy of the Ear

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Area of Science:

Audiology
Acoustics
Biomedical Engineering

Background:

Limited user acceptance of hearing devices is a significant challenge.
Poor acoustic environment preservation is a primary cause of low user acceptance.
Existing hearing aids and assistive listening devices often fail to provide natural sound perception.

Purpose of the Study:

To present and evaluate an earpiece prototype designed for acoustical transparency.
To achieve an audio perception similar to the unaided ear.
To address the issue of poor sound quality in current hearing devices.

Main Methods:

Technical measurements using an advanced dummy head.
Listening tests comparing the prototype with a simulated open ear canal.
Evaluation involved ten normal-hearing subjects, including five expert listeners.

Main Results:

Technical evaluations confirmed successful achievement of acoustical transparency.
Psychoacoustic tests indicated no significant distinction between the prototype and open ear conditions for communication sounds.
The prototype effectively preserves the natural acoustic environment.

Conclusions:

The developed earpiece prototype represents a functional acoustically transparent hearing system.
It provides a foundation for future hearing systems integrating high sound quality and hearing support.
The device minimizes disturbance to external sound perception, enhancing user experience.
