Statistics suggest that 3.55 million Australians suffer from hearing loss. Of course, the severity varies from person to person and so does the treatment. Many can be treated medically through medicines and surgical procedures while some need hearing aids for listening properly. Around 40% hearing loss is due to over exposure to loud noise (more than 85 dB) and so personal care should be taken to avoid such situations, be it at home or work.

Checking the hearing aid scenario, an estimated 90% devices are digital confirming the use of digital technology in treating hearing loss. The emergence of digital hearing devices dates back to 1987 with digital signal processing (DSP) device. But, it's due to its uncomfortable design it did not gain any popularity. A decade later popular styles of digital devices called Behind The Ear (BTE) and Completely-In-The-Canal (CIC) were launched and have seen tremendous success.

Appreciated by both clinicians and consumers, these had higher signal processing and thus gave excellent results. There are several advantages of digital hearing aids compared to their analogue counterparts. These reduce the unnecessary noise facilitating clear listening to the actual voice. A very big leap in listening technology, these devices reduces the environmental sounds and microphone noise.

The major advantages of digital hearing aids can be summed as follows:

Digital Noise Reduction: This feature is aimed to increase audibility in low frequencies or specific bands while the device catches steady state signals. Quite an improvement over the analogue devices, these digital devices aid in reducing annoyance and improve speech recognition in case of non fluctuating noises.

Digital Speech Enhancement: Another striking feature of digital hearing aids is  their ability to increase the intensity of certain segments of speech. This can be done on temporal or spectral content. It is still a new feature and is known to the many device users.

Digital Feedback Reduction: There is a certain level of feedback while the hearing device comes in proximity to objects or due to certain jaw movements. Digital devices aid in reducing this feedback and thus helps in clear listening.

Fashionable options: The digital hearing devices have come up with many designs and colours giving a chic feel and look to the user. Now, the hearing aids have no longer remained a matter of embarrassment or are just a medical device but are actually a style statement that one is happy to wear.

To sum up, with advancement in technology, the digital devices have not only become more effective but also suffice the need of charisma. available in different sizes, shapes and colours these hearing aids give high quality results for all genres. Loved by the voguish generation which relates everything with fashion, these devices form a cult and are here to stay!!
