WHAT IS SPATIAL HEARING LOSS?
A loss of spatial hearing presents itself as the inability to distinguish spatial cues. People with spatial loss of hearing find it difficult to tell who is speaking in a noisy room or where a certain sound is coming from. This condition prevents sufferers from cutting out background noise in crowded places such as restaurants and airports. Perhaps surprisingly, the ear is not the source of spatial hearing loss. The brain is actually the culprit – the pathways that interpret sound are the root of spatial loss of hearing.
This type of hearing loss can be found in any age group, but is especially common in young children and adults over age 60. For children with this condition, it can be difficult to excel in school, due to the inability to hear the teacher through the background noise.
Audiologists use a test called the Listen in Spatialized Noise-Sentences, or LiSN-S, test to diagnose spatial hearing disorders. The LisN-S test determines how a person uses pitch and spatial cues in order to pick out certain sounds from background noise. This lets the audiologist determine just how severe the person’s loss of spatial hearing is.
Spatial hearing loss does not always occur on its own. These conditions include loss of high-frequency and/or low-frequency hearing. These issues can be treated with hearing aids, which helps with the spatial loss of hearing as well. Hearing aids aren’t a magic bullet for everyone. In fact, for some sufferers of spatial hearing loss, hearing aids can actually make the problem worse.
Spatial hearing loss happens often in older people, due to the natural aging process and subsequent damage to the audio nerve. Medications, injury, vascular insufficiencies, or underlying medical conditions and diseases are also factors in the loss of spatial hearing. It is essential to seek medical attention immediately if you or your loved ones notice

sudden hearing loss. Illness, infection, or blockages can cause sudden hearing loss – and they respond positively to immediate treatment. If sudden hearing loss is not quickly diagnosed and is caused by an infection or other underlying illness, it could progress to inner ear involvement permanently damaging auditory nerve pathways and resulting in permanent deafness or spatial hearing loss.
Unilateral hearing loss puts you at an increased risk of spatial hearing loss as well – so it is again essential to immediately get help if you notice any sudden changes in hearing. It can be challenging to know if your hearing has changed, so go get hearing tests regularly.
