Summary
Osseointegrated auditory devices improve hearing thresholds and speech recognition. While processor power output correlates with bone conduction thresholds at higher frequencies, its link to speech recognition gain is less clear.
Area of Science:
- Audiology
- Biomedical Engineering
- Otolaryngology
Background:
- Osseointegrated auditory devices utilize bone conduction for hearing improvement.
- Factors influencing sound transmission are known, but processor power output's role is less understood.
Purpose of the Study:
- To investigate the relationship between osseointegrated auditory device processor power output and achieved hearing improvement.
Main Methods:
- 44 patients with percutaneous Baha® 5 devices were assessed.
- Pre- and post-operative hearing thresholds (pure tone, free-field), speech recognition (quiet/noise), direct bone conduction, and processor power output were measured.
Main Results:
- Significant hearing improvement was observed in pure tone thresholds and speech recognition.
- 63.64% of patients achieved air-bone gap closure.
- A correlation between bone conduction thresholds and processor power output was found at mid/high frequencies (≥1000 Hz), but not with functional or speech recognition gain.
Conclusions:
- Osseointegrated auditory devices effectively enhance hearing thresholds and speech recognition, including in noisy environments.
- A link exists between bone conduction thresholds and processor power output, particularly at higher frequencies.
- Further research is needed to fully understand the factors influencing speech recognition gain from these devices.

Sound Intensity Level
4.3K
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...

The Auditory Ossicles
2.1K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Hearing
53.2K
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.

The Cochlea
46.2K
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.

Auditory Pathway
5.9K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

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...
