They played different music mixes to listeners with and without hearing loss and found that those with hearing loss preferred louder lead vocals, higher frequencies, and sparser mixes with fewer frequencies overall. Previous research has found that music steadily shifted to quieter vocals and louder instrumentals leading up to 1975, meaning today's music may be less accessible to those with hearing loss.

But today's interfaces are slow and, from electrodes placed on the scalp, can detect letters only. The speech generated is robotic and affectless. Neuroscientists have now shown that they can reconstruct the song a person is hearing from brain recordings alone, holding out the possibility of reconstructing not only words but the musicality of speech, which also conveys meaning.

In two new studies scientists explain why this is the case and how we might be able to change it.

Participants in this study reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.

These new findings are an important piece of the puzzle in explaining what happens in the ear in hearing impairment caused by harmful noise, and may in the long run contribute to diagnosing noise-induced hearing injury.

Previous studies indicate that this early auditory activity -- before the onset of hearing -- provides a kind of training to prepare the brain to process sound when hearing begins.

This syndrome includes malformations of varying severity, affecting different parts of the face. Its causes and modes of transmission are still poorly understood. An international collaboration has discovered that pathogenic variants of the FOXI3 gene -- responsible for the development of the ear -- cause one form of this developmental disorder. The scientists were also able to identify the modes of transmission of the disease when this particular gene is involved.

Researchers are now getting closer to identifying the mechanisms that may promote this type of regeneration in mammals.

They point to a vicious cycle involving stress reactions and sleep disturbance as a potential cause. If you live near a busy road, it may increase your stress levels and affect your sleep. When we are under stress and sleep poorly, we may be at a higher risk of developing tinnitus.

New findings show that genetic testing is a valuable tool in determining prognosis for a child's hearing loss and in predicting how useful a cochlear implant could be for that child's understanding of speech. With genetic diagnosis, it is possible to anticipate future hearing loss across sound frequencies, progression with age, and severity.

Using a mouse model of a human congenital disorder that displays deafness, the researchers identified two master genes controlling hearing function, which opened a new pathway for diagnosis of deafness and balance problems, and possibly to the effects on stem cells in other tissues and syndromes.

While less perceivable, objective combination tones are also generated by some musical instruments. Researchers have now used violins to explore these rarely studied objective combination tones. They found that the combination tones produced by higher-quality violins were much stronger and clearly audible and powerful air resonance and violin sound quality are linked. The higher-quality violins produced a stronger air resonance due to several factors, including structural material and crafting techniques.

The study found that a single dementia risk factor could reduce cognition by the equivalent of up to three years of aging.

If people think they hear someone else's voice when they speak, they do not strongly feel that they caused the sound. This could be a clue to understanding the experience of people who live with auditory hallucinations and could help to improve online communication and virtual reality experiences.

Cochlear implants -- considered the gold standard of treatment -- are small, electronic devices surgically placed under the skin that stimulate nerve endings in the ear to provide a sense of sound. A new study demonstrates the need for early cochlear implant use for deaf children, regardless of developmental impairments.

But scientists now have discovered a single master gene that programs ear hair cells into either outer or inner ones, overcoming a major hurdle that had prevented the development of these cells to restore hearing.

Among the various causes of tinnitus is stress. What's unclear, however, is whether the psychological impacts of the pandemic such as stress actually worsened tinnitus. Researchers assessed whether the severity of tinnitus, as measured using ratings of tinnitus loudness, annoyance, and effect on life, was influenced by the lockdown related to pandemic. Results do not support the idea that the pandemic led to a worsening of tinnitus and the mean scores did not differ significantly for the groups seen prior to the pandemic and during lockdown.

Thanks to direct stimulation of the auditory nerve, it enables more than half a million people worldwide to hear, even though those affected were born deaf or deafened. Researchers have developed a method to convert the stimulation electrodes of common CIs into electrochemical sensors. With the help of this novel sensor function, the functionality of cochlear implants could be monitored directly in the inner ear in the long term.
