Summary
The Vibrant Soundbridge is a semi-implantable hearing device suitable for hearing loss up to 70-dB HL. While not outperforming conventional hearing aids audiometrically, patients reported high satisfaction due to comfort.
Area of Science:
- Audiology
- Biomedical Engineering
- Otolaryngology
Background:
- The Vibrant Soundbridge is a semi-implantable hearing device with an external audioprocessor linked to an internal transducer.
- A key advantage is the ability to update the audioprocessor, facilitating upgrades from analog to digital technology.
- This study involved replacing a 2-channel analog audioprocessor with a 3-channel digital device in 14 patients.
Purpose of the Study:
- To evaluate the performance and patient satisfaction of a 3-channel digital audioprocessor in the Vibrant Soundbridge system.
- To compare the device's efficacy with conventional hearing aids in patients with sensorineural hearing impairment and external otitis.
Main Methods:
- A prospective clinical study was conducted on 14 patients with moderate to severe sensorineural hearing impairment.
- Measurements included device gain across input levels and speech perception in quiet.
- Comparative assessments were made with conventional hearing aids where feasible.
Main Results:
- The 3-channel digital audioprocessor demonstrated suitability for hearing loss up to 70-dB HL, providing gains of 15-30 dB HL.
- While audiometric results with the Vibrant Soundbridge were not superior to conventional devices, patients reported significant comfort and usability.
- Five patients underwent direct comparison with conventional hearing aids, while nine used the Vibrant Soundbridge due to contraindications for ear molds.
Conclusions:
- The Vibrant Soundbridge is a viable option for individuals with hearing loss up to 70-dB HL.
- The device offers substantial patient satisfaction, particularly for those experiencing discomfort with conventional hearing aids.
- Audiometric performance did not show a significant advantage over traditional hearing aid devices.

01:31Hearing
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.
01:01Perception of Sound Waves
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 frequency...

01:17Auditory Perception
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 cochlea, a...
01:21Perceiving Loudness, Pitch, and Location
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 identifying...
