Low frequency hearing loss

• Men’s voices
• Traffic noise
• The bass in music

The main symptom is difficulty hearing deeper, lower-pitch, sounds, such as those outlined above and:

• Planes flying overhead
• Household appliances
• Vowel sounds (spoken at a lower pitch than consonants)
• Phone conversations
• Thunder

You might also find that you struggle to hear conversations when you’re in a group of people, somewhere with lots of background noise, or in a noisy environment.

The severity of this type of hearing loss also depends on the type of low frequency loss you’re experiencing. Some people only suffer mild loss, which can often be difficult to detect as they don’t notice any issues so are less inclined to seek help, while others suffer a significant or severe loss.  

Despite these difficulties, this type of hearing loss doesn’t usually impact your ability to understand normal speech - though you may find face-to-face conversations easier to follow than those held over the phone or online.

Low frequency hearing loss has two main causes, which depend where in your ear the problem starts. These are:

Conductive - which is caused by problems in your middle ear.
Sensorineural - which is caused by damage to your inner ear, particularly to your auditory nerve, cochlea or the hair cells that help transmit sound waves to your brain.

Conductive low frequency hearing loss often happens as a result of problems like:

• Secretory otitis media - where an infection causes fluid to build up in the middle ear, and prevents your eardrum from vibrating properly
• Otosclerosis - where your stapes bone (a bone in your middle ear) overgrows. This can be caused by autoimmune problems, genetics and viral infections

Sensorineural low frequency hearing loss is usually caused by:

• Ménière’s disease - a disease caused by a build-up of fluid in the inner ear, which, alongside low frequency hearing loss, can also cause tinnitus and vertigo
• Genetic mutations - genetic diseases such as Wolfram syndrome and Mondini dysplasia can affect hearing
• Ramsay Hunt Syndrome - a disease caused by the herpes zoster virus infecting the facial nerve
• Sudden loss of hearing - this can cause vertigo, tinnitus and low frequency hearing loss
• Age - hearing changes with age, and this relates to low frequency sounds as well as high frequency sounds

If you’ve noticed any change in your hearing, whether it’s come on suddenly following a period of illness, or is something that’s happened gradually, it’s important to speak to your doctor to address any underlying cause.

One of the first steps towards treating low frequency hearing loss is to have a hearing test. This can determine the extent of the loss, and therefore the type of treatment you need.

Of course, treatment also depends on the cause of the condition. Some causes - such as secretory otitis media - can be reversed or get better on their own, while others - such as those that result in conductive low frequency hearing loss - may need surgery.

Our audiologists will assess your hearing and analyse your results so that they can find the best way to help you manage your condition, such as using hearing aids to amplify the low-pitched sounds.
