What is the principle of the Welch Allyn Audiometer?
The audiometer operates on the concept of measuring a person’s hearing sensitivity, or the lowest volume they can tolerate at various frequencies. The person taking the hearing test responds to each pure-tone sound by clicking a button or raising their hand. The audiometer produces these sounds at particular frequencies and intensities. Read about the Maico audiometer.
A transducer, headphones, and a control panel make up the audiometer. Several sound frequencies and intensities are produced with the transducer. The patient responds by signaling when they hear the sound, which is delivered to their ears using headphones. Take a look at RA660 audiometer.
The patient’s reactions to various sound frequencies and intensities are recorded by the audiometer, and this data is plotted on an audiogram—a graphical illustration of a patient’s hearing sensitivity. The audiogram assists medical specialists in both diagnosing and evaluating the patient’s hearing impairment. Another principle you should know is about the smartlyte electrolyte analyzer.
Parts of the Welch Allyn Audiometer
- Control Panel: the specialist operates the gadget’s settings and features which consist of a display screen, buttons, and knobs.
- Headphones: Sends auditory stimuli to the patient’s ears. They are made to suppress outside noise so that the patient can easily hear what is being spoken.
- Transducer: Produces pure-tone sounds at various frequencies and intensities. It is in charge of getting the sound into the patient’s ears and is attached to the headphones.
- Patient reaction button: The patient presses this button or switch when they hear a sound. It enables the audiologist to precisely capture the patient’s comments.
- Power cord: The audiometer is connected to a power source using the power cord.
- Data storage: The user is able to save and retrieve patient data in this way, including audiograms and test results.
How to use Welch Allyn Audiometer
- Preparation: Make sure the patient is at ease and aware of what to expect before beginning the hearing test. Inform them of the testing process, what they must perform, and how the results will be used.
- Set up the audiometer: Make sure the headphones and other equipment are correctly attached before connecting the audiometer to a power supply.
- Choose the test: Depending on the patient’s age and hearing condition, choose the right test. The audiometer may provide a range of tests, including bone conduction, speech, and pure-tone testing.
- Play the sounds: Play it in each ear of the headphones, one at a time. Tell the patient to react to the sound by raising their hand or pressing a button.
- Record the outcomes: On the audiogram, note the patient’s comments. Do the same for the opposite ear. Another brand of audiometers you should look at is the GSI audiometers.
- Interpreting the findings: Consider the patient’s age, gender, and medical history as you interpret the findings of the hearing test.
- Discuss the outcomes: If required, offer treatment recommendations and go over the test results with the patient.
