A new hearing test called wide-band reflectance could improve diagnosis of middle ear infections and other hearing disorders. The test uses softer sounds to trigger a middle ear reaction, allowing doctors to make a diagnosis without exposing patients to intense noise.
A Northwestern University study found that many older women have undiagnosed and untreated hearing loss, which can lead to depression and emotional problems. The researchers suggest that public policy should include hearing care as part of all health maintenance plans.
A computer model developed by Jay Rubinstein suggests that increasing the signal pulses from external processors can produce more independent neuron activity, similar to natural acoustic stimulation. This breakthrough could lead to substantial improvements in all types of sound coding for people with cochlear implants.
Research suggests that older people's tolerance for rock music is lower due to physiological changes, such as presbycusis, which affects hearing. Additionally, emotional factors play a role in auditory perception, with older adults potentially being more irritated by rock music due to unfamiliarity.
The University at Buffalo's Center for Hearing and Deafness has received a $5.7 million grant to study acquired hearing loss, affecting 28 million people in the US. The center will investigate four projects on peripheral and central auditory system function.
Researchers found that senior citizens rated rock music much higher on a loudness scale than younger people. As people age, their tolerance for loudness decreases due to common hearing loss conditions like presbycusis, which distorts certain sounds and makes low frequencies more noticeable.
A free orientation program developed by UF professor Alice Holmes aims to increase patient satisfaction among hearing aid users. The four-session program provides realistic guidance on using hearing aids, adjusting settings, and preventing communication breakdowns.
Researchers at University at Buffalo found that the brain center responsible for hearing can reorganize itself after damage to the auditory nerve endings. The damaged nerve endings take longer to recover, but the brain recovers sooner, within five days.
Researchers found that R-PIA increased the activity of glutathione, an antioxidant that absorbs free radicals, providing enhanced protection from damage. Animals treated with R-PIA recovered their hearing faster and more completely than those treated with saline, showing less damage to sensory cells.
Researchers found that mice without thyroid hormone receptor beta are deaf, even though they appear healthy. The study suggests that this gene controls hearing development, and its loss may cause human genetic forms of deafness.
