Difficulty Hearing With Background Noise: Is it Hearing Loss?
Trying to have a conversation in a noisy environment, like a loud restaurant, can be extremely frustrating. You often have trouble understanding the person you’re speaking with and keep saying, “Huh?” or asking them to repeat themselves.
So, is it just extra noise? Or could it be a sign of hearing loss or auditory processing difficulty?
Hearing loss and auditory processing difficulty can happen at mild to moderate levels, which you may not notice until you’re struggling to have a conversation with someone while in a crowd.

Why Can’t You Hear People With Background Noise?If you can’t hear conversations when there’s background noise, it’s likely because your ears have trouble filtering out the environmental sounds. Trouble hearing even with mild background noise is often the first symptom of moderate hearing loss or auditory processing disorder (APD). Since difficulty hearing can get worse if left untreated, you should get your hearing checked by a doctor to find out the true cause. After all, you regularly get your eyes and teeth checked, so why not your ears?
How Your Brain Processes Different NoisesHere’s a quick rundown of what happens when you hear different sounds: Your body has two main processing centers for sound: the ear and then the auditory cortex in your brain. Your ear turns sound waves into chemical signals, which go to your brain and are processed in the auditory cortex. When you hear a noise, sound waves enter your outer ear and travel through your ear canal to get to the eardrum. The eardrum sends the vibrations from the sound waves to the middle ear, where they’re amplified and sent to your cochlea inside the inner ear. The cochlea has fluid that vibrates with the sound, which causes sensory hair cells to bend. That sends chemical signals through the auditory nerve to your brain’s auditory cortex for the next part of processing. Next, your auditory cortex takes those chemical signals and basically “decodes” the information so you can better understand it. One of the jobs your auditory cortex has is filtering out unnecessary and irrelevant information, such as background noise. In other words, your brain dims the sounds in the background so you can focus better on important sound patterns, like speech. If you can’t hear a conversation even with mild background noise, then you may have damage in one of these sound processing centers.
Auditory Processing DisorderAuditory processing disorder (APD) is a condition where your brain has trouble processing the auditory signals it gets from your ear. That’s to say that your ear works fine, but your auditory cortex can’t decode the sounds well enough. People with APD often notice symptoms starting in childhood, but it can happen in people of any age. Symptoms of APD include:
- Mixing up similar sounds (such as “hand” and “plan”)
- Difficulty following conversations or responding quickly
- Trouble identifying where a sound came from
- Difficulty hearing with background noise
High-Frequency Hearing LossHigh-frequency hearing loss has to do with the ear’s inability to hear high-pitched sounds, and it’s usually caused by damage to the hairs in your inner ear. It affects up to 14% of people under the age of 65 and 30% over the age of 65. Two common causes of high-frequency hearing loss are aging and noise exposure. Symptoms of high-frequency hearing loss include:
- Hearing what’s being said but misinterpreting the words
- Difficulty understanding speech in noisy places
- Trouble hearing consonants (such as s, h or f)
- Asking others to repeat themselves, speak slowly, or enunciate
- Tinnitus (ringing or buzzing in the ears)
Other Types of Hearing LossAPD and high-frequency hearing loss are two of the most common causes of difficulty hearing with background noise. But your symptoms could be caused by other types of hearing loss, which an audiologist can diagnose:
Sensorineural Hearing LossSensorineural hearing loss (SNHL) is an umbrella term that means hearing loss caused by damage to the inner ear nerves and hair cells, and it includes high-frequency hearing loss. Other types of SNHL, such as congenital sensorineural hearing loss or sudden sensorineural hearing loss, can also cause difficulty hearing in social situations. Those conditions are less common than high-frequency hearing loss, which accounts for roughly 90% of hearing loss cases. But note that all types of sensorineural hearing loss can be tested for and diagnosed by an audiologist.
Conductive Hearing LossConductive hearing loss happens when an obstruction in the ear, such as wax buildup, causes hearing impairment. It can also be caused by:
- Ear infections
- Damage to the outer or middle ear
- Muffled hearing
- Difficulty hearing softer noises
- Feeling of stuffiness in the ears
- Ear pain
Possible Causes of Hearing LossHearing loss can be caused by several factors, including genetics, your environment, and other medical conditions. Here are a few major players in hearing loss:
Noise ExposureExposure to loud noises remains one of the most common risk factors for hearing loss. Over time, coming into contact with sounds like lawn mowers, large engines, and loud music can damage the hairs in the inner ear and lead to hearing loss.
Age and Other Medical FactorsAlmost 50% of individuals over the age of 75 suffer from some form of hearing loss. Age-related hearing loss, or presbycusis, affects both ears and often runs in families. Other conditions that can develop as you age, such as diabetes, stroke, and hypertension, can also cause hearing loss.
MedicationsMany medications have been associated with hearing loss, including aspirin (at very high doses), some antibiotics, and medicines used to treat cancer. Some drug-induced hearing loss can be reversed, but other damage is permanent. If you experience hearing loss as a side effect of a new medication, speak with your doctor right away.
GeneticsAccording to the Centers for Disease Control and Prevention (CDC), genetics play a role in 50% to 60% of hearing loss in babies. Genetic hearing loss is often caused by mutations in the genes that contain instructions for the proper functioning of the ear. In most cases, genetic hearing loss symptoms appear in childhood.
Foreign Objects and DamageObstructions in the ear canal interfere with your body’s ability to turn sound waves into chemical signals for your brain. Foreign objects stuck in the ear can lead to infections and temporary hearing loss.
Negative Effects of Hearing LossLoss to any one of your five senses can create a negative ripple effect in your daily life. In particular, hearing loss and symptoms like difficulty hearing with background noise can cause problems communicating and even lead to increased isolation. Social isolation resulting from hearing problems can impact mental health and self-esteem in people of all ages, and even contribute to the development of dementia as you age.
Treatment Options for Moderate Hearing LossIf you have trouble keeping up with conversations in most environments, including those with low background noise, you may be experiencing moderate hearing loss. If your hearing loss is caused by an obstruction or infection, then it may be cured by cleansing or medication. Otherwise, your doctor will recommend treatments to manage the loss. Here are the common treatments used to manage moderate hearing loss:
Hearing AidsHearing aids help you manage moderate hearing loss by amplifying the sounds that you have trouble hearing. Like glasses, they’re a device that you wear to improve your senses. Hearing aids use microphones to amplify the sound waves from your environment and send them through the middle ear. Most hearing aids are digital and can be calibrated according to your level of hearing loss. You’ll need to have your hearing tested by an audiologist or hearing aid dispenser before you get hearing aids so they can eliminate other causes of hearing loss. A specialist can also help you choose the best hearing aid for you and monitor a trial period to see if it’s the right solution.

I have constant difficulties with my hearing when there is background noise both in the office and in restaurants/pubs. My wife is adamant that this is directly linked to my scuba diving as we have to regularly equalize our ears during the dive. Could this be a cause and if it is, is it reversible?
Alwyn – thank you for your comment! I am sorry to hear you are experiencing difficulty hearing in noisy environments. The research we have seen has shown that scuba diving very rarely causes hearing loss on its own, however, it is possible under certain circumstances. I encourage you to book a hearing test and talk with a professional to learn more about the type of hearing loss you may be experiencing. That will help you best understand your treatment options and whether diving plays a role.
My hearing loss during background noise environments varies according to the frequency of the voice I’m listening to. With many voices I have trouble with discrimination (can hear but can’t understand) while with other voices I can hear clearly. However, both hearing clinics I attended for background hearing loss assessment used only one voice. As it happened I heard that voice clearly and so was evaluated as having no hearing loss discrimination. Why didnt they use voices of different frequencies?
Hi Girard! I’m sorry to hear you’re having issues hearing different voices in background noise. LACE uses a few different voices (male, female, and child) throughout the training. You could try purchasing LACE a go through a few sessions to see if it works for you. We have a 5-day money-back guarantee. If you decide LACE isn’t right for you, just email firstname.lastname@example.org within 5 days of purchase for a full refund.
My hearing test is normal but I have difficulty hearing and following conversations in loud noisy environments or competing conversations. I had a very large brain tumor removed surgically and subsequent proton beam radiation. My MEE hearing tests were normal but I continue with the above difficulties. Is there a hearing aid that could help me?
