There are many examples in nature of animals using objects to boost their calls, but situations where animals use objects to amplify sound are not nearly as frequent. Livescience reports on research showing how a social species of Costa Rican bats uses funneling leaves as a type of ear horn to hear other members of their group.

It seems that ear damage from noise and the drug ecstasy make for a deafening mix. American researchers at Wayne State University in Detroit, Michigan (USA) have shown that ecstasy, chemically MDMA (3,4-methylenedioxy-N-methylamphetamine), worsens hearing loss related to noise trauma.

The ciliated cells in the cochlea are the motor for hearing. The internal cells transmit sound to the brain, while the external ones amplify the sound. Without them, our surroundings would be nearly impossible to hear (the sensitivity is increased by approximately 60 dB).

New compound with potential to prevent noise-related hearing loss

Research

Scientists at the Oregon Hearing Research Center at the Oregon Health and Science University (USA) carried out a new study in mice to assess the molecular mechanisms underlying noise-induced hearing loss, with associated tinnitus and sound hypersensitivity.

Type 2 diabetes mellitus and hearing loss

Research

A recent review and meta-analysis published in The Laryngoscope has found that the incidence of mild hearing loss is significantly higher in individuals with type 2 diabetes than in age-matched controls, and that auditory brainstem response (ABR) wave V latencies are longer in diabetics.

The Italian SUN Test out to conquer America

Researchers at the Italian National Research Council working at the Milan Institute of Biomedical Engineering (ISIB) have developed a new screening method that is taking the analysis of how well people understand speech in noisy environments out into the real world.
It is being used more and more, including by academics worldwide, and has recently been highlighted in the American Journal of Audiology.
