If you are in a busy restaurant, on a congested subway platform, or strolling along a well-traveled street, there are situations where the noise around you is overwhelming. People who use hearing aids are particularly sensitive to this problem as it becomes difficult to differentiate between meaningless noise and important sound. Digital noise reduction technology embedded inside hearing aids is one approach to combating this problem. It allows the wearer to block unwanted noise and focus on specific sounds.
Conversational speech and meaningless noise follow different sound patterns, which digital noise reduction technology is able to pick up on. This is easy to do when speaking to someone in a quiet room as the speech signals are the only sound around. However, when conversing in a noisy environment, your digital noise reduction equipped hearing aid can tell that there is unwanted sound present. The hearing aid makes the necessary adjustments on its own using built-in software and reduces the volume associated with the noisy channels.
There is no hearing aid that can completely block out noise interference, but this function can still go a long way when it comes to lessening the frustration that comes from communicating in noisy areas. The general consensus among hearing aid wearers with this technology is that speech sounds better and background noise is less overpowering.
Users are most pleased with their results when the device is used to counteract a constant background noise. While digital noise reduction may not be completely effective in reducing the impact of loud music or nearby conversation, it can greatly reduce steady sounds such as an air conditioner or a motor.
Users may wish to consider utilizing other noise reduction strategies in conjunction with their digital noise reduction capable hearing aid. In restaurants it is usually possible to request a table in a quieter area or away from music speakers.
Digital noise reduction technology is not perfect, but it can go a long way in helping to counteract the unwanted noise you encounter in your day to day life.
