The technology advancements have become the root for few health-related issues. Listening to any audio with high volume—at nightclubs, bars, sports events, and many others—are the reasons that affect the hearing ability. The hearing aid is a device that is worn on the ear to improve the hearing ability. Hearing aids have become high-powered and efficient devices today.

Listening to people in a noisy environment is the major issue for the people who can’t hear. The advanced hearing aids can reduce the unwanted noise from the surroundings. People can have a relaxed conversation despite the loud environment without being distracted by any noise. The hearing aid has come with an added advantage of geotagging that can help the users to remember the location.

The past hearing aids were capable of hearing the noise in only one direction while the advanced hearing aids of today that come with microphones enable a sound in any direction to be heard clearly. This will be an advantage for those that are driving; it also helps in the situation where someone speaks from behind. This can also be a safety accessory because the person can be aware of location or vehicle when unexpected incidents happen, and they can keep the people informed regarding the situations. Hearing aids have become comfortable in wearing as they are small in size and are customized to meet the users’ requirements. Completely-in-Canal (CIC) and Behind-the-Ear (BTE) are the hearing aid models which can do the job of the receiver and cannot be visible to the others.

The present hearing aids have more connectivity options through which the people can directly stream from devices like smartphones and laptops. Bluetooth and Wi-Fi are the connectivity options by which the hearing aid can be connected through an application on the devices that can control multiple configurations on hearing aid. Bluetooth enabled hearing aids—can improve sound quality and reduce background noise, allow to stream from any other Bluetooth-enabled devices directly to hearing aids. Present hearing aids are water resistant; they will continue to work even when exposed to moisture for a short period. Hearing test applications came into existence through which people could test their level of hearing loss and use a tool to prepare for the real test. The new hearing aids have advanced algorithms to hear voices and reduce background noise, and digital technology also allows creating different customized devices to address personal hearing needs.
