Introduction
my brother and his ears
My brother (and his ears)

Meet the guy that introduced me to classical music 65 years ago

predicament
Predicament

& the germ of an idea

  • My visit to Edmonton
  • Aging ears – and in a hospital
  • What, no iPod?
  • How hearing loss became a virtue
meanwhile at the hospital
Meanwhile at the hospital
  • Physical discomfort
  • No tv
  • No CDs
  • No audio-visual enjoyment available
  • My iPod unsuited to Earl’s ears, with or without hearing aid.

So I went shopping for a remedy. –None existed!

disconnects
Disconnects

Hearing aid culture

  • Invisibility
  • Low power/tiny battery
  • Not mp3-friendly
  • Limited dynamic range

tiny transducers

low voltage

  • Annoying to wear; easy to misplace
  • Associated with ageism

iPod culture

  • Cool
  • Visible & fashionable
  • Superb sound quality for ‘normal hearing’
  • Music, music, music
  • Trendy earphones

But

  • neglects personal hearing deficits

not enjoyed yet by persons with hearing loss
Not enjoyed (yet)by persons with hearing loss

Such as

  • Rock Musicians
  • Age related (Boomers)
  • Pilots
  • Occupational damage
  • Slow degradation over time

Most everyone,

sooner or later

In fact

  • Most people don’t know what they’ve been missing
  • They just gradually got used to
      • less brilliance
      • lack of localization
      • reduced clarity
      • muffled sounds

hearing acuity
Hearing acuity
  • Often assumed
  • Not normally measured until deafness is suspected

Frequently a matter of opinion

rather than accurately assessed.

so we set out
So we set out
  • To match the sounds of the world
    • To Earl’s hearing spectrum

By using musician-quality equipment.

(i.e. audiophile, hi-fidelity, studio-quality stuff)

How we did it (eventually)
  • Implementation
    • Developed a special, prototype interface device to precisely compensate

(SpectraPhonics Normalizer technology)

(as used by artists and audiophiles)

technology gerontology
Technology & Gerontology
  • Today’s media - MP3/Video players, video games, downloaded content, and live performances rely on hearing.
  • Yet hearing profile (loss) has been and continues to be neglected by these markets
    • Except for hearing aids
    • Which are marketed as if for the infirm, the old, the defective.

our positive lifestyles vision
Our ‘positive lifestyles’ vision

to make it cool to be custom fitted for ‘ear glasses’.

  • Let’s enjoy 20/20 listening; Let’s redefine ‘normal’!
