With the Welch Allyn AudioScope 3 you can screen your patients quickly and accurately-and with more flexibility. It's a simple procedure that takes only seconds, and in many instances may be third party reimbursable. You can even use the instrument to visualize the patient's ear canal before and during the screening.
Because AudioScope 3 has three screening levels in one unit (20, 25 and 40dB HL), you can screen all of your patients with a single instrument. And the tones are presented at random intervals so your patients can't second guess their hearing screen. This varied timing means improved results. Welch Allyn has also built in a 1000Hz pretone, presented at 20dB HL above the screening level, so your patients have the opportunity to practice listening before they're actually screened.
The Welch Allyn AudioScope 3 represents the latest in audiometric screening technology, combined with the reliability for which Welch Allyn has become known.
It's a Simple Procedure That Takes Only Seconds
- Seat the patient in a quiet room.
- Attach appropriate AudioSpec® to AudioScope 3.
- Instruct patient on method of response.
- Retract pinna.
- Select desired screening level.
- Insert AudioScope 3 into ear canal.
- Visualize tympanic membrane.
- Depress start button.
- Observe tone indicators and patient's responses.
- Screen opposite ear.
- Failure at any frequency necessitates rescreen.
- Second failure may indicate need for referral.
Over 20 million people in the United States (one out of every 15 individuals) suffer from hearing loss. Many other countries report similar statistics.
Hearing problems can affect an individual's social adjustment, speech and Ianguage development, academic progress, as well as the psychological well-being of that individual and his or her family.
Fortunately, most hearing problems can be very successfully addressed through medical treatment and/or aural rehabilitation.
The crucial element and first step is early detection, and it is here that professionals and paraprofessionals play a vital role.
While audiologists and otolaryngologists are specially trained for testing and treating ear diseases, the primary care setting is ideally suited for first and early detection of the problem, since people frequently visit these groups: pediatricians, family practitioners, general practitioners, speech-language pathologists, nurse practitioners, physician assistants, public health personnel, school health nurses and volunteers.
With a fast, simple, accurate method of hearing screening, early detection and appropriate referrals can be more efficiently and effectively accomplished.
TRADITIONAL HEARING TESTING
Tuning forks were one of the first methods used to determine the type of hearing loss. They may still be used by some to differentiate between conductive and sensorineural losses. However, they have in great part been replaced by the audiometer.
Traditional audiometers produce pure tones of varying frequency and intensity. Frequency is measured in Hertz (Hz) or cycles per second, and is perceived as pitch. Human hearing ranges from approximately 20 to 20,000 Hz. Intensity is measured in decibels (dB) and is perceived as loudness.
Most often, hearing is measured by specialists in terms of threshold, or the faintest sound which an average listener can just hear in the quiet. Thresholds are measured at various frequencies, usually in the speech range (500 Hz to 4000 Hz) and just beyond (125 Hzto 8000 Hz).
The magnitude or degree of loss is recorded on a form called an audiogram. Measurements are made by air conduction, where the sound is introduced through a headphone into the ear. Measurements may also be made by bone conduction, where the sound is introduced through a vibrator which is placed on the mastoid bone behind the ear. By comparing these two measurements, the type of loss (conductive, sensorineural or mixed), can be determined.
The Welch Allyn AudioScope 3 provides a unique means for accurate and efficient early detection of hearing loss. AudioScope 3 provides screening at the speech frequencies of 1000, 2000, 4000 and 500 Hz respectively, at a fixed decibel level. Choices of decibel levels include: 20 dB HL, 25 dB HL and 40 dB HL. Prior to the screening tones a practice tone or pretone (PT) is delivered at 1000 Hz and at 20 dB HL above the screening level.
Package includes AudioScope 3, set of AudioSpec® Specula, 110-130 V Charging Transformer, Recording Forms, and Optional Charging Stand (Model 92680 only).
