If you have hearing difficulites, a standard hearing test may not be enough to pick up any hidden hearing loss. At Harley Street Audiovestibular Clinic, we have invested in the latest equipment and have the clinical expertise to assess your hearing and ears in further detail including extended range audiometry, tests of inner ear function (otoacoustic emissions) and nerve reflex assessment (acoustic reflex testing).
Do you have hearing loss earlier than expected? Were you born with hearing loss? Have you an assymetrical hearing loss? - one side worse than the other? Do you have any other symptoms with the hearing loss? Have you had your hearing loss investigated properly by a medical specialist?

Conductive Hearing Loss
A problem with the sound going into the inner ear. Causes include ear canal problems such as infections and middle ear problems such as effusions. Specialised tests can help to determine the movement of your ear drum and function of your middle ear muscles to diagnose conditions such as otosclerosis.
Sensorineural Hearing Loss
Hearing loss arising from the inner ear cochlea. It tends to be a permanent hearing loss. It can be due to medical causes, genetics, medications (ototoxicity) or age related deterioration amongst others. Aetiolgoical investigations including specific blood tests & scans help to determine the cause and associated conditions.
Congenital Hearing Loss
Congenital hearing loss tends to be present at birth and related to genetics or events around childbirth. It may sometimes present later in childhood or early adulthood. Early accurate diagnosis & medical investigations arer vital.
Genetic Hearing Loss
Genetic hearing loss may present at birth or even in early adulthood. Sometimes it only presents with exposure to certain ototoxic medications such as gentamycin. Genetic tests are available for some types of hearing loss.
Asymmetrical Hearing Loss
Hearing loss which affects just one ear or affects one ear more than the other can indicate a potential underlying problem with the auditory nerve and its pathways to the brain. Appropriate investigation and imaging at an early stage is key.
Progressive Hearing Loss
Gradually deteriorating hearing loss can be due to many factors including genetics, noise exposure, medications, medical comorbidities and infections. A detailed history, examination and appropriate investigations including imaging is required for accurate diagnosis.
Auditory Neuropathy (ANSD)
Hearing problems more than expected by traditional hearing tests can be due a problem of the auditory nerve sending signals to the brain. This could be due to a nerve or brain problem & requires detailed investigations including nerve conduction studies (ABR) & reflexes as well as a full neurological examination.
Auditory Processing Disorders (APD)
APD is characterised by difficulty in understanding sounds, and in particular speech sounds. Hearing and cochlear function tends to be normal. The auditory nerve tends to be normally functioning. Detailed tests and appropriate investigations are required prior to diagnosis.
