The shape of the plot reveals the degree and nature of hearing loss, distinguishing conductive hearing loss from other kinds of hearing loss. A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x ...
The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause.
Cytomegalovirus (CMV) infection is the most common cause of progressive sensorineural hearing loss in children. It is a common viral infection contracted by contact with infected bodily fluids such as saliva or urine and easily transmitted in nurseries and thus from toddlers to expectant mothers.
Gene therapy has allowed several children born with inherited deafness to hear. On Tuesday, the Children's Hospital of Philadelphia announced similar improvements in an 11-year-old boy treated there.
Bone conduction is also a good option for someone who cannot use traditional air conduction hearing aids. [15] Bone conduction devices are also used to help people with single-sided deafness, who have a non-functioning inner ear on one side. In this situation, the device picks up sounds on the non-functioning side and sends them as vibrations ...
In children, early diagnosis and treatment of impaired auditory system function is an important factor in ensuring that key social, academic and speech/language developmental milestones are met. [43] Impairment of the auditory system can include any of the following: Auditory brainstem response and ABR audiometry test for newborn hearing
An experimental gene therapy being developed by a Chinese company restored hearing in children with congenital deafness, researchers working on a clinical trial reported on Wednesday, adding to ...
