“To perform the testing, it must be quiet in this box, but finding the right material for the sound insulation portion of the design was a difficult task.
“We were able to achieve the overall sound insulation, light weight, and slim design we were after, and an overall sound insulation level of 40 to 60 dBs after the installation of Acoustiblok,” van Oosten said. “Acoustiblok was just what we needed.”
The OtoCube weighs less than 15 kg (33 pounds), according to Ad Vreeswijk, ABC International Trading B.V.’s General Manager Europe. The sound insulation qualities of the Acoustiblok, Vreeswijk says, help the OtoCube set a new standard in precision, usability, and sound insulation for ambient noise.
Programming a cochlear implant is a technical intervention, which is done only by a trained audiologist. Achieving the best possible programming of the bio-electrical device is the audiologist’s primary goal when testing and calibrating each individual’s cochlear implant. The OtoCube provides a portable device that can reach many patients when access to a testing booth is impractical or impossible.
The OtoCube prototype, currently being clinically tested in several European clinics, is expected to be marketed by 2013.
There are approximately 240,000 cochlear implant recipients worldwide, including 41,500 adults and more than 30,000 children in the U.S. Only one in approximately 130 people around the world who could benefit from a cochlear implant has received one. However, since 2004, U.S. health policies have been put in place to increase CI recipients by 10 percent.

Acoustiblok, Inc., a NASA spin-off company, has been providing high quality noise abatement products since 1998, earning the industry’s highest ratings from architects, builders, and consumers. Acoustiblok is a proprietary viscoelastic polymer material with a high density mineral content, heavy and yet extremely flexible. As sound waves cause the Acoustiblok material to flex, internal friction occurs and the acoustical energy is transformed into immeasurable trace amounts of heat (adiabatic).
Just one, 1/8 inch layer of Acoustiblok in a standard wall will result in more sound reduction than 12-inches of poured concrete. Environmentally friendly, Acoustiblok contains no lead, barium, or asbestos, is UV resistant and impervious to water and mold; it is UL rated and classified in the US and Canada (CUL) for virtually all wall, floor, and ceiling installations.
