Introduction

QSA® stands for Quiet Sound Amplifier. The BEAN
is a personal sound amplifier that automatically
enhances soft sounds. Loud sounds pass through
as though nothing is in the ears.

The BEAN provides the highest fidelity sound
amplification available at any cost. The sound
quality of the BEAN is superior to that of all
known custom-fitted devices, and is available
without medical referral or prescription.

The circuitry in the BEAN incorporates a patented
new ultra-low-distortion output amplifier, along
with all of the important features and benefits of the
original K-AMP
ago by Mead Killion, Ph.D., Sc.D.(hon), a well known
engineer and professor of audiology. No circuitry,
including digital technology, has proven superior to
the sound quality of K-AMP circuitry – the engine
of the BEAN.

Intended Use

The Bean has high-frequency emphasis for soft sounds,
so the faint sounds of speech can be heard more
easily – especially if the speaker is farther away than
desirable or speaks very softly. The most common
example is someone asking a question from another
room. Soft speech can also be heard in a house of
worship, classroom, courtroom, lecture hall, theatre,
or TV dialog. For many users, the BEAN is like a pair
of reading glasses that are only used part of the time.

Adjusting to the BEAN

• Most BEAN users find the eartips comfortable
to wear for many hours right away. Others do not.

• Take your time.

• You may want to wear the BEAN for short periods
until you can wear them for as long as you wish.

• If the eartips that come on the BEAN are not
comfortable or do not seal well in the ear, try other
eartip styles supplied to determine which size is
right for you.
