Prepared for

Positive Lifestyles Panel (Friesen Conference 23 April 2009)

ByMorley Lipsett (semi-retired)

SFU Centre for Policy Research on Science and Technologyand

Earl Lipsett (retired musician/educator)

With inspiration from

Naftaly Ramrajkar (Product developer, audiophile & sage)

My brother (and his ears)

Meet the guy that introduced

me to classical music

65 years ago

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

My ‘cool’ gear (on the plane)

Meanwhile at the hospital

Physical discomfortNo tvNo CDsNo audio-visual

enjoyment availableMy iPod unsuited to

Earl’s ears, with or without hearing aid.

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

And this begins our story -

Hearing aid culture

InvisibilityLow power/tiny batteryNot mp3-friendlyLimited dynamic range

tiny transducerslow voltage

Annoying to wear; easy to misplace

Associated with ageism

over timeMost everyone, sooner or later

In factMost people don’t

know what they’ve been missing

They just gradually got used to

Hearing acuity

Often assumedNot normally measured until deafness is

suspected

Frequently a matter of opinion rather than accurately

assessed.


Yet audiograms are like eye exams


Person with hearing loss

Person with ‘normal’ hearing

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)

Technical objectives


Restore audiophile listening experience

i.e. beyond today’s youthFor recorded performances

andLive events

How we did it (eventually)

Implementation

1. Developed a special, prototype interface device to precisely compensate (SpectraPhonics Normalizer technology)

2. Fed studio quality earphones/headphones (as used by artists and audiophiles)


Obvious, perhaps, but unavailable

We got it to work!

At first with

headphones

and CD’s

Then with

mics, re

ady for

rehearsals


Resulting experience (field trials)


Like putting on glasses and seeing clearly - again.

20/20 listeningThrilling!

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 marketsExcept for hearing aidsWhich are marketed as if for the infirm, the old, the

defective.


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’!

Any questions?

Does anybody here care to get involved in this work?
