From Horsepower to Hearpower, Part 2: Amplification for Clarity and Hearing Preservation |
| |
by H. Christopher Schweitzer, PhD, and Desmond A. Smith |
| |
A discussion of the physical processes involved in our amazing range of hearing, from soft to loud. Additionally, an explanation of how temporal integration—as implemented in a new amplification approach designed to exploit psychoacoustics—provides for hearing protection and intelligibility enhancement. |

A New Compression Strategy Based on a Guided Level Estimator |
| |
by Christian Stender Simonsen, MScEE, and Thomas Behrens, MScEE |
| |
A new compression strategy combines linear and non-linear amplification in new ways. In steady acoustic environments, the compressor operates in a nearly linear manner; however, if the level of the acoustic environment changes more than a given amount, the gain swiftly follows. The system is designed to allow for a high global compression ratio, while maintaining near-linear performance for locally stable environments. |
