Understanding how hearing aids work shows how hearing aid technology is advancing at a greater speed than how it used to be with new functions and features that help people with hearing loss go through their daily activities just like everyone else. With the speed that it is advancing, many might not be caught up with the new technological updates about hearing aids in Singapore

Can a hearing aid be used to hear higher frequencies?

Hearing aids in general is not able to process the broad range of pitches or frequencies that a regular human ear can process due to the circuit. There has been research that suggests that ears with hearing loss might not have functioning hair cells to create high-frequency sounds even if they are made louder. Hence, someone with hearing loss might find difficulty in hearing children or women talk due to their high-pitched voices. 

However, manufacturers have invented a new technology to address this issue called frequency-lowering. Frequency-lowering technology allows the hearing aid to capture high-frequency sounds and adjusts them into lower-frequency regions instead of making the high-frequency sounds louder which would not be as effective. Hence, high-frequency sounds can be heard at lower frequencies where hearing is much better.

At The Hearing Centre, we provide an extensive selection of hearing aids that are equipped with frequency-lowering technology and many other latest technological features that modern hearing devices have to offer.

Do we normally hear better by bone or air conduction?

An example of how bone conduction science is being advanced with technology.

There are two significant types of conductions in hearing which are bone conduction and air conduction. Air conduction is the most common type of conduction where sound vibrations enter our ears and travel to the eardrums. Natural sound waves are carried through the ear every day.  

Bone conduction is the conduction of sound to the inner ear generally through the bones of the skull which allows the user to recognize audio without the ear canal being blocked. This type of conduction transmission occurs regularly as sound waves vibrate our bones in the skull, however, it is difficult for a normal individual to recognize sound being conveyed through the bone as compared to the sound being transferred through the air in the ear canal. 

Normally, we hear better through air conduction as the inner ear is much more sensitive to sound via air conduction as compared to bone conduction. However, in a case where there is purely unilateral conductive hearing loss, the ability to hear a bone-conducted sound is improved.

How do digital hearing aids work?

Components of a digital hearing aid

There are three main parts of how sound is amplified through a hearing aid. First, a microphone will be present to receive the sound and convert it into a digital signal where the amplifier would then increase the strength of the digital signal. Lastly, a speaker will produce the amplified sound into the ear of the user. 

Digital hearing aids can now be customized to an individual’s level of hearing loss. At The Hearing Centre, upon completing a free hearing test with us, our audiologists will program the hearing aids to the specific degree and pattern of hearing loss that is seen from the test results. Digital hearing aids now have many automatic features such as being able to adjust the volume and programming for better hearing in various environments.

Do hearing aids reduce background noise?

There are many types of hearing aids, all with different and unique functions of their own. While many people may assume that hearing aids simply make sounds louder for the wearer, there are some hearing aids that now offer noise-canceling features that allow the wearer to tell the different sounds apart. These type of hearing aids has noise reduction algorithms in place that helps improve the signal-to-noise ratio during a conversation in environments that are noisy. 

Hence, this means that it allows the hearing aid to amplify sounds that the wearer would want to listen to. After using it for a few weeks, the brain would be able to adapt to the hearing aids and the sounds that it hears. Book a free hearing test and consultation with a certified audiologist at The Hearing Centre to find out more about hearing aids with noise-canceling functions.
