Sound Pharmaceuticals are developing a drug that can protect against hearing loss. Otoprotection drug trials have been conducted on animals and have shown success. Two of four potential drugs already have been approved for human use to treat other diseases. In addition, they are also examining the regeneration of auditory hair cells.
Endevco and National Instruments develop Plug-and-Play sensors
Endevco and National Instruments are developing plug-and-play sensors. The sensors have in-built low-cost memory chip that contains information about the transducer stored in the Transducer Electronic Data Sheets (TEDS). Information such as calibration data will be automatically read by a signal conditioner or analyzer, thereby eliminating calibration errors. The TEDS format conforms to the IEEE standard P1451.4, which was in part developed by National Instruments.

Laminated steel plates make products quieter
MSC Laminates is an off shoot from Material Sciences Corporation that makes laminated steel products. Their QuietSteel product is damping material that has been sandwiched between two layers of sheet steel. I have heard that this product is used in every oil pan on US cars. Recent news articles have appeared describing how Ford are using it in the firewall of their larger vehicles to reduce noise transmitted into the cabin.

Making aircraft quieter
The European Commission’s SILENCE program, Significantly Lower aircraft Environmental Noise Community ExposuRe, aims to reduce the noise from commercial aircraft. The research program involves 51 companies. Rolls Royce and Boeing developed a modified engine that was flight tested on a Boeing 777 that resulted in jet noise reduction of 4 dB and fan noise reduction by 13 dB.

Acoustic Microscope
Researchers have developed a technique that uses an ultrasonic probe to examine tissue samples. The advantage of this technique is that tissue can be examined in-situ, without removing samples and that the tissue does not need staining. The resolution of the technique is useful to examine cells, down to about 0.1 micron.
