Automotive gauge-based sound pressure instrument
First Claim
1. An gauge-based instrument for measuring the sound pressure within a vehicle comprising:
- a cylindrical gauge housing, said cylindrical gauge housing having a front portion, a rear portion and a diameter, said front portion constructed and arranged for securement of a faceplate;
a faceplate, said faceplate having sound pressure level markings thereon, said markings being visible through said front portion of said housing;
a gauge motor disposed adjacent to said faceplate;
a signal processing means for receiving a signal indicative of the sound pressure level within said vehicle, said circuit controlling said gauge motor based on said signal;
a pointer extending out of said gauge motor and movable by said gauge motor;
wherein said sound pressure level gauge is mountable within a standard gauge mount.

Abstract
The instant invention provides a novel and useful gauge-based sound pressure instrument that is mountable within preexisting pod, cup and panel gauge mounts, thereby allowing a vehicle owner to customize a vehicle for multiple uses. The sound pressure instrument receives a sound pressure wave through a microphone mounted at about the drivers'"'"' ear level and processes the resultant electrical signals through a signal processing means into groups of digital pulses. The digital pulses are displayed on an analog and/or digital display in real time. Associated with the signal processing means is a monitoring means which indicates when the received sound pressure waves are above predetermined levels. Associated with both of these means is an peak storage means which monitors each group of digital pulses and also any signals provided by the monitoring means. Utilizing these, the peak storage means stores the highest achieved sound pressure level in each group of digital pulses which may be recalled at a later time.
