If you have hearing loss, generally you will have difficulty hearing in background noise. If you have hearing that is classed as 'normal' - when focusing on speech or one sound source, you can filter out the background noise automatically. People with hearing loss struggle to do this without support from hearing aids.
For example, it can be a challenge for those with hearing loss to have a conversation in a busy restaurant. Hearing in background noise is, therefore, a top priority for those with hearing loss.
However, using hearing aid features and modern technology they can distinguish and understand speech and noise. This article discusses the extra options and hearing aid features that can tackle background noise.
Wearing hearing aids helps you distinguish the direction, sources of sound and filter out the unwanted background noise - and all whilst allowing you to feel a part of your environment. Today's hearing aid technology offers different settings and filters so that you can have full control of the way you want to hear - usually using your mobile phone hearing aid app. However, some modern hearing aids can adjust automatically.
One of the main features of hearing aids is background noise reduction. This smart technology is called digital signal processing or DSP. This identifies and understands background noise in the environment you're in and lowers the level of volume. Giving you better listening comfort and less listening effort.
How does DSP do this? The most popular way to filter out background noise is using directional microphones, which are used to focus on sound or speech in front of you instead of behind you. A good audiologist will ask what your common environments are to customise your hearing aid settings to reflect this and support your hearing better.
They can also now customise programs that enable you to tackle sporadic listening situations where there is a lot of background. But to simplify, between the two microphones within your hearing aids you can quickly identify the direction of sound and get amplification or reduction in a certain direction.
This technology keeps getting faster and more intelligent with the improvement of processing chips and more research and investment into algorithms.
Because it's enough to just turn up the volume, right? Well, in short, no. Hearing aids also include volume control, but it's not used for what you might expect. For example, if you turn up the volume on your TV with your remote control it will automatically make all sounds louder. A volume control setting on your hearing aid will turn up or down both high and soft frequencies.
This ultimately makes it harder for people with hearing loss to process. For example, if you raise the volume, it can make it harder to hear your conversation and this is because most speech is in low frequencies.
Hearing aids of today have very smart and powerful processors that distinguish the difference between your background noise and speech. This leaves you with better speech clarity and focus. The main job of hearing aids is to help filter out background noise and enhance speech, making it easier for people to understand what is being said in noisy environments. This is called Improved Speech Understanding.
What is even more impressive is that big technology doesn't have to mean big cumbersome hearing aids anymore. Discrete, small, and invisible hearing aids incorporate this kind of technology too.
Hearing aids that help with background noise and improve speech understanding have several benefits. These are:
What about the best hearing aids for background noise reduction? There are a lot of hearing aid brands that reduce background noise and improve speech understanding successfully. Each manufacturer uses different technology to tackle background noise - below are a few examples.
Each Phonak hearing aid has forward-facing directional microphones that share data with the other hearing aid. By working like this, they then decide from which direction sound is coming and reduce the amplification of any sound or speech that isn't coming from that direction. They call these microphones beamforming directional microphones.
Oticon tackles background noise by segmenting and distinguishing what variations of sound you can hear using artificial intelligence, called Deep Neural Network (DNN) to give you better clarity and focus on speech.
This type of technology has been trained to understand millions of sounds of everyday life and learn. This means that the AI can correctly identify what is in your environment to then amplify and focus on what it thinks you would rather hear.
Sounds we all hear and walk amongst every day. Environments like restaurants, train stations, or all the sounds you hear while walking down your street. Oticon's processor is also 50 times faster than Phonak's scanning the environment over 100 times per second.
The result is an intelligent hearing aid that balances, organises, and prioritises the most important sounds that are unique to you, as well as supporting your own brain's cognitive health. Providing you with clear sound and speech - a deep neural network can always follow the conversation and understand sound.
Resound hearing aids reduce background noise by using their directional microphones and All Access Directionality technology. This means that one hearing aid is in a directional mode that focuses on the sound or speech coming from the direction you are looking at. The other hearing aid is in an omnidirectional mode which enables you to still hear 360-degree sound.
The idea behind this technology is that it learns which hearing aid microphone to use as the focus, by predicting what sound or speech you want to focus on.
Hearing aids can help reduce background noise by using advanced algorithms to filter out unwanted sounds and enhance speech. Some hearing aids also have features such as noise reduction and directional microphones that can help to further reduce background noise.
However, it's important to understand that the effectiveness of the noise reduction features can vary depending on the specific hearing aid, technology level, and the individual's hearing loss. It's always best to consult with an audiologist to determine the best course of action for your specific needs.

As well as amplifying sounds, hearing aids can filter out background noise. Most hearing aids now reduce background noise as well as help you to distinguish what sounds you can hear and from which direction they are coming from.
DSP (digital signal processing) enables the hearing aid to know the difference between background noise and speech. It does this by turning down the volume when there is no speech and up when there is within background noise.
Hearing aids that help with background noise and improve speech understanding have several benefits. Such as: easier conversations, less listening effort, prevents cognitive decline and increases self-esteem in social gatherings.
