Abstract
A system for capturing high quality sound information from an impact includes a microphone stand and microphone array. The microphone stand is configured so that the microphone array arranged thereupon is focused on a single point so that ambient noise may be reduced.
Claims20
A sound capturing system comprising:
- a microphone stand for supporting a plurality of microphones, the microphone stand having a base having a first curvature and an arm associated with the base, the arm having a second curvature;
- the arm positioned substantially perpendicular to the base;
- wherein the first curvature and the second curvature are selected so that any microphone positioned on the microphone stand is focused on a single point a known distance from the microphone stand.
A microphone stand comprising:
- a base;
- an arm associated with the base, wherein the base occupies a first plane and the arm occupies a second plane, and wherein the first plane is different from the second plane;
- the base configured to support a first microphone, the first microphone directed to a first focal point;
- the base having a first curvature;
- the arm configured to support a second microphone, the second microphone directed to a second focal point;
- the arm having a second curvature;
- and
- wherein the first curvature and the second curvature are selected so that first focal point and the second focal point are substantially the same point.

A method for detecting a high quality impact sound generated by a striking object impacting a projectile at an impact location, the method comprising:
- deploying a plurality of microphones, wherein each microphone in the plurality of microphones is positioned a known distance from any other microphone in the plurality of microphones, and wherein each microphone in the plurality of microphones is focused on the impact location;
- receiving the impact sound at one or more of the microphones in the microphone array so that one or more of the microphones generates an impact signal;
- communicating the impact signal to an analysis module;
- and
- analyzing the impact signal to determine the high quality impact sound.
