Hearing aids and how they work with noise

As technology is increasing and more innovative products are coming into the market, hearing aid wearers may not have to cope with deciphering a voice in the midst of constant background noise. Many people with hearing loss – whether it is very mild or severe – often have the most difficulty when they are out at a restaurant, in a meeting or a social gathering where background noise can't be avoided. While most devices were unable to perform well in the past, directional microphones and other hearing aid technology have made it possible for people with hearing loss to enjoy going out again.

Most hearing aids on the market today have a directional microphone option that users can switch on and off to hear sounds from all sides or just in front of them. According to Better Hearing Institute, directional microphones can reduce noise from the sides and/or back by three to four decibels. However, this feature needs to be turned on and off because there are only certain situations where it will come in handy, like at a dinner or gathering.

Digital signal processing

Digital hearing aids have advancement recognition systems that can differentiate the sound between background noise and speech. Digital signal processing (DSP) automatically turns down the volume when it suspects background noise.

Two hearing aids

After being examined for your hearing loss, you may notice that one hear is better than the other. However, your audiologist many recommend you get two devices. This is partially because using two hearing aids will make it easier to hear in noise. Two hearings aids amplify the sounds from both sides, so that users can locate where it is coming from.

FM and loop systems

Assistive listening devices like FM and loop systems work with hearing aids to improve hearing when users are out in a public setting. Both pick up the sound from where it originates and transmits the sound through a device. Loop systems are used with hearing aids with t-coils, so the user doesn't need any additional equipment.

As technology continues to improve, hearing aid wearers are getting closer to normal hearing. Constant advancements are making it easier for people with hearing loss to comprehend speech and enjoy the little things in life. Find an audiologist in your area and discuss the best option for your condition.
