Abstract: A system and method for providing a translated or calibrated signal to a bone conduction transducer. The frequency of an audiometer output signal is detected and attenuation and amplification calibration values may be determined from a lookup table as a function of this frequency. Characteristics of the output signal may then be varied as a function of the calibration values to provide a translated or calibrated signal. This signal may then be provided to an exemplary bone conduction transducer such as a piezoelectric, electrostrictive or other electroactive bone conduction transducer.

Abstract: A method for applying liquid, foam and/or gel forms of asbestos digestion chemicals through painted, coated or otherwise protected or encapsulated surfaces of asbestos-containing materials. The method includes forming an injection aperture in the encapsulating material and contacting the hazardous asbestos-containing material with asbestos digestion material through the injection aperture. As a result of the treatment, the asbestos digestion material converts the hazardous asbestos-containing material into non-hazardous material.
