               Please follow the drop down link (left menu)  to read a couple of papers uploaded 14/June/2020 on Production Vehicle Audio System based on the methods outlined in US Patent No. 9,688,072 "Loudspeaker Rectification Method"

This is an audio system diagnostics QC process ideal for "duplicated rooms" such as vehicles & cinemas, can also be used to calibrate mobile devices.

See more below or on the "News" page.

Welcome. This little web site is simple, just to promote self & ideas.

Brief Intro: 

I specialise in audio technology consulting. I have worked around much of the globe in R&D & corporate management in Professional (Pro-Sound), Automotive OEM and Consumer Audio.

AES: I remain a Life Member the Audio Engineering Society (AES) Standards but after many years, in March 2022 I have retired from  positions as; Technical Council Chair, Technical  Committee Chair: TC-LH (Loudspeakers and Headphones), Standards Committee Chair: SC04-03 Loudspeaker Measurement and Modelling

 Technology skills;

- well versed in acoustics, electro-mechanics, electronics.

- inventor and co-inventor on 16 issued U.S. patents to date (many more international patents, and a few more inventions in the pipeline)

- acoustics expertise with hands on experience:

Transducer design - from sub-components of motors, voice-coils, spiders, cones, surrounds etc. to completed woofers, mid-drivers,  tweeters, compression drivers, horns etc..

Audio system design (integration of loudspeakers, horns, crossovers,  enclosures, rooms or vehicles).

Audio system tuning ranging from automotive OEM to commercial sound systems in auditoriums.

Proprietary Audio Product Technologies - Portfolio for license (just ask):

Vehicle - Audio System Quality Verification: Ready for "The Internet of Things" cloud based diagnostics, calibration & warranty management. (Patent pending process).

Alternative topology loudspeakers

Vibration reduced woofers - minimizing panel vibrations. Very effective for vehicle doors & rear decks.

Look at the Equity Sound Investments - history page for some info on the BOND power cooled loudspeakers that were developed for pro-audio many years ago.

Seeking Licensing Partners:

Audio System Validation, Calibration and Diagnostics - >> US Patent No. 9,688,072  - Available for license.

- A Cloud Based or Embedded data analytics and test protocol to diagnose and if necessary, calibrate production vehicle audio systems.

- Not a system tuning tool but rather, it is a method to match production system performance with the original reference system on which they are based.

- can be used in B&A at end of line and by dealers to diagnose and trouble shoot audio systems.

- - - Value Proposition:

- is a protocol & method valued by QC, not system engineering per se.

- can virtually eliminate false warranty (NTF) claims reducing warranty costs (arguably, 50% to 80% of all audio system warranty costs)

- Side benefits:

 - - Potential to cost reduce transducers by opening tolerance for certain attributes for less eol rejects and, less sub-component rejects.

 - - improved customer satisfaction.
