Why Consider Offering the QSA?

Why Consider Offering the QSA?

There is a significant opportunity to offer the QSA Quiet Sound Amplifier as a low-cost easy to use, introduction to amplification to those patients currently walking out without a solution.

The QSA® Quiet Sound Amplifier® can provide that one click of clarity. As a personal amplification device–also known as a Quiet Sound Amplifier–The QSA features a built-in sensor that automatically adjusts to the surrounding noise level. It amplifies soft sounds, while keeping the volume steady on louder noises or even reducing it for extremely loud sounds such as fireworks or the strike of a drum. Moreover, it boosts soft high-pitched sounds heard in speech, which helps provide clarity for conversations, particularly in less-than-ideal listening environments.

The T-coil QSA can be used with hearing-aid compatible telephones and loop systems. Loop systems take their name from a loop of wire that is placed around a room or large area. The loop sends an electromagnetic signal to the QSA, which then changes that signal to sound. The benefits are improved hearing in reverberant conditions or when a talker is too far away to be heard clearly with amplification.

Instructions For Use

TIPS for Using The QSA:

  • The QSA turns off when the battery door is open. The QSA turns on when the battery door is closed.
  • A user may hear feedback that sounds like whistling while inserting the device. This is completely natural.
  • It may be necessary to take the device out of the ear to flip the switch. (Some users can use the switch while it is in the ear, but many cannot.)quick start step1

1. Battery and ON/OFF

  • Open the battery door — located on the bottom of the device.
  • Remove yellow tab from battery.
    Note: The battery has a flat side and a round side.
  • Place battery in the door and close.
    Note: Door will not close if the battery is inserted incorrectly.

Turn ON by closing battery door. A working battery must be in place. Turn OFF by opening battery door.
Note: Battery does not need to be removed if the door is open far enough to turn off the device.

Tip:
Always carry spare batteries.
Low-battery warning: When you hear a low rumbling sound, change the battery (refer to manual).

2. Eartips and Proper Insertion

When changing eartips make sure the eartip fits securely on the stem of the device.
quick start step 2a

quick start step 2c

The eartip that is most comfortable and seals the ear is the best choice.
Note: Eartips are reusable. Replace 3-flange eartips every 60-90 days and foam eartips regularly.
To properly insert: Pull ear up and out. Using a twisting motion, position the device horizontally in the ear with the switch toward the back of the ear.
Note: Feedback (whistling) may be heard while inserting the device until it is fully sealed in the ear.

quick start step 2b

Tip:
Deeply-sealed eartips reduce the "hollow" sound in your voice. If this happens, try to achieve a deeper seal. You may want to try an eartip with a long stem.

3. Operating the Switch

A. The Standard QSA

Normal setting — flip the switch toward the front of the device.
quickstart_step3_std_up

High setting — flip the switch toward the back of the device for more sound.
quickstart_step3_std_down

Tip:
Some people can flip the switch when the device is in the ear, but it is not unusual that you will have to take it out of your ear to change the switch position.

B. The T-coil QSA

Microphone position — flip the switch toward the front of the device.
quickstart_step3_std_up

  • 15-dB amplification and treble boost for soft sounds
  • No amplification for loud sounds

Telecoil position — flip the switch toward the back of the device for T-coil use.
quickstart_step3_std_down

  • T-coil active
  • Microphone disabled

Using the Telephone

The phone can be used with the QSA in either the M or T position.

M: Hold the phone up to the ear just as you normally do. If there is a small amount of feedback (whistle) when the phone is close to the QSA, re-position the QSA for a better seal. Some people choose to hold the phone out at a slight angle from the ear.

T: Flip the switch back to use with hearing-aid compatible phones and loop systems.

Tip:
Some people can flip the switch when the device is in the ear, but it is not unusual that you will have to take it out of your ear to change the switch position.

Frequently Asked Questions

Who is the Ideal Candidate for a QSA Device?

The QSA amplifier was developed for those who need a boost in sound for soft speech in a house of worship, classroom, courtroom, lecture hall, theatre or TV dialog. For many people the QSA is used only part of the time. A QSA user wants to communicate easily and effectively with family, colleagues and acquaintances in business and social situations.

How does the QSA work?

The QSA comes pre-programmed. Advanced circuitry in the QSA amplifier includes built-in sensors that detect and amplify only soft sounds, remaining acoustically transparent for loud sounds. Loud sounds pass through as though nothing is in the ear. There is instantaneous recovery from impact noise like hand claps and door slams, and slow recovery for loud sustained sounds with release at just the right time so speech remains clear and completely natural.

What is a T-coil model?

The T-coil QSA can be used with hearing-aid compatible telephones and loop systems. Loop systems take their name from a loop of wire that is placed around a room or large area. The loop sends an electromagnetic signal to the T-coil QSA which then changes that signal to sound. The benefit is improved hearing in reverberant conditions and large areas where traditional amplification is not effective.

Is the QSA Amplifier Good for Music?

The QSA device has true high fidelity. It has an extended bandwidth for maximum clarity, and it can process peak sound inputs to a very high level (115 dB) without distortion, which means you receive superior sound quality and clear music reproduction.

Frequently Asked Dealer Questions

How do I benefit from providing the QSA Quiet Sound Amplifier?

QSA is something to offer to patients who need some hearing help but choose not to purchase hearing aids. In the past, if a patient didn't purchase hearing aids, the patient left without any hearing assistance. With the QSA Quiet Sound Amplifier, patients who choose not to purchase hearing aids don't leave the office without a solution. They came to you because they had a problem, and they don't leave empty-handed.

The QSA fills a gap in product offerings. There is an untapped niche market of patients with a small problem, but who do not want to purchase programmable hearing aids costing thousands of dollars. Now they can purchase a sophisticated, low-cost personal sound amplifier from you, to use when they need it.

The Quiet Sound Amplifier can be a marketing tool. You can advertise to the huge market of baby-boomers who need a little hearing help in certain situations, but who wouldn't otherwise consider purchasing a hearing aid. You can make those people your patients when you otherwise might not ever see them in your office.

The QSA doesn't have the look or features of a hearing aid. There is no confusion as to what the patients are buying. There's a clear division between this device that offers a bit of help to those who need it, and a programmable hearing aid with multiple memories, noise-reduction, feedback management, streaming, etc. You can justify the cost of the QSA and you can also justify the cost of your hearing aids. They're different devices for different applications.

Happy QSA users are more likely to return to you when they need more hearing help than a personal sound amplifier provides. They trust you because the product was fairly priced and high quality. And, patients who really do need hearing aids but are not quite ready may upgrade to hearing aids after a trial with the QSA.

How do my patients benefit?

Patients can buy a high-quality, low-cost device that is simple to use. They will have hearing assistance which is appropriate for their hearing levels. They don't have to leave your office without a solution to fit their needs.

Patients experience excellent sound quality, which means they're more likely to benefit from it in their daily lives and they're more likely to believe hearing assistance is helpful. Personal sound amplifiers with limited bandwidth and poor fidelity provide a poor listening experience, and when patients experience poor sound quality, they're less likely to believe hearing assistance is helpful.

Patients can return to you if they have a problem; they're not left on their own. Patients can rely on you to be their hearing healthcare provider, both now and in the future.
