A study reported in the SPIE Journal of Biomedical Optics by researchers at Medizinische Hochschule Hannover on the use of green laser light in improving hearing is noted in Audiology Online.
The study ("Green laser light activates the inner ear") shows how visible light is used to induce an optoacoustic effect that activiates the cochlea, improving hearing performance in noisy environments and for sounds more complex than speech.
Authors of the JBO article are Gentiana Wenzel, Sven Balster, Kaiyin Zhang, Hubert Lim, Uta Reich, Ole Massow, Holger Lubatschowski, Wolfgang Ertmer, Thomas Lenarz, and Guenter Reuter. The group will present a paper on "Laser hearing aids" in the conference on Advanced Technology and Instrumentation in Otolaryngology: Lasers, Optics, Radio Frequency, and Related Technology at SPIE Photonics West in San Francisco, California, in January.
Lubatschowski will present a plenary talk in the LASE symposium at Photonics West, on the future for ultrafast lasers in ophthalmology. Lubatschowski and Ertmer serve on Photonics West program committees and, along with Massow, are authors of multiple papers at the symposium. All three are SPIE Members.
