               Please follow the drop down link (left menu)  to read a couple of papers uploaded:
- Production Vehicle Audio System based on the methods outlined in US Patent No. 9,688,072 "Loudspeaker Rectification Method",
This is an audio system calibration and diagnostics QC process ideal for "duplicated rooms" such as vehicles.

See more below or on the "News" page.

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

Brief Intro: 

I specialize in audio technology consulting. I have worked around much of the globe in R&D & corporate management developing transducers, systems, mentoring engineering staff and advising corporate strategy in Automotive OEM, Professional (Pro-Sound) and Consumer Audio.

Audio Engineering Society (AES): After a few decades serving AES committees, in March 2022 I retired from all chair positions;  Chair, Technical Council, Technical  Committee.  Chair, TC-LH (Loudspeakers and Headphones). Standards Committee Chair: SC04-03 Loudspeaker Measurement and Modelling. I remain an AES Life Member and wish the AES well as it transitions to focus on recording & academics. 

 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 Diagnostics and Calibration:  Cloud based diagnostics, calibration & warranty management.

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:

Software Defined Loudspeaker - >> "Loudspeaker Rectification Method" US Patent No. 9,688,072  - Available for license.
- A Cloud Based or Embedded Audio System Validation, Calibration and Diagnostics  method for data analytics and test protocol to diagnose and if necessary, calibrate production vehicle audio systems.
- Ideally suited for development as plugin apps for AAOS, QNX, DSP Concepts etc.

- In summary, 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 .
-- by dealers to diagnose and trouble shoot audio systems.
-- potentially, by end user (owner) as a downloadable app. (requires OEM & system supplier data for targets).

- - - Value Proposition:
- A protocol & method valued by QC.
- Can virtually eliminate false warranty (NTF) claims reducing warranty costs (arguably, 50% to 80% of all audio system warranty costs)
- Can be used by engineering reduce to time for "re-equalizing" tasks :
----     When sourced components are changed during life cycle.
----    Optimize performance when trim is changed, eg. upholstery, sunroofs etc.

- 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.
--  Brand consistency
