Title: Innovations by Kate D Fischl

Introduction

Kate D Fischl is an accomplished inventor based in Cambridge, MA (US). She has made significant contributions to the field of audio technology, particularly in the area of recording impulsive sounds. With a total of 3 patents to her name, her work focuses on addressing critical issues related to noise-induced hearing loss (NIHL).

Latest Patents

One of her latest patents involves methods and apparatus for recording impulsive sounds. Loud sounds with fast rise times, such as gunfire and explosions, can lead to NIHL. Current models do not adequately explain how these impulsive sounds cause NIHL, making it challenging to predict and prevent it in hostile environments. Fortunately, Kate's innovative system can record these impulsive sounds using a compact, portable device that acquires, digitizes, and stores high-bandwidth audio data. This system can be mounted on a helmet or other articles, allowing for the recording of hours of audio data at a bandwidth of 20 kHz or higher. This bandwidth is sufficient to capture sounds with rise times of less than 50 ms. An analog-to-digital converter (ADC) digitizes these broadband audio signals at a rate of 40 kHz or higher to preserve the impulse information. A processor then transfers the digitized samples from a buffer to a memory card for later retrieval using an interrupt-driven processing technique.
