Introduction
Hearing is an essential part of how we interact with the world. It allows us to communicate effectively, enjoy music, stay alert to our surroundings, and maintain emotional connections with our loved ones. Unfortunately, hearing loss can develop gradually, and many people don’t realize they have a problem until it begins to interfere with daily life. Sometimes, it’s not until we start missing important words in conversations or find ourselves asking people to repeat themselves that we understand something is wrong. Pure Tone Audiometry (PTA) is one of the most effective, widely recognized, and reliable ways to measure hearing ability. It assesses how well you can hear sounds at different pitches and volumes, providing a clear and detailed picture of your hearing health.
At Insight Diagnostics and Labs in Pallavaram, we have invested in advanced audiometry technology and created a comfortable, soundproof environment to ensure precise results. Our team of trained audiologists and technicians takes the time to explain every step of the process, ensuring you feel at ease throughout your test. We serve patients across all age groups—whether it’s a parent concerned about their child’s speech development, an adult noticing subtle hearing changes, or an elderly person experiencing age-related hearing loss. With accurate results and clear guidance, we help you take the right steps towards better hearing health and improved quality of life.
Understanding Pure Tone Audiometry (PTA)
Pure Tone Audiometry is a hearing test that determines the softest sound you can hear at various frequencies, from deep bass tones to high-pitched sounds. It is a subjective test, meaning it relies on your responses to the sounds presented. During the test, you will wear headphones connected to an audiometer—a specialized machine that produces tones at different pitches and volumes. The audiologist will ask you to indicate whenever you hear a sound, even if it’s very faint. These responses are recorded and plotted on an audiogram, a graph that visually represents your hearing thresholds for each frequency.
The results of the PTA test provide critical information about the type and degree of hearing loss. It can distinguish between conductive hearing loss (caused by problems in the outer or middle ear) and sensorineural hearing loss (caused by issues in the inner ear or auditory nerve). This distinction is important because each type requires a different treatment approach. At Insight Diagnostics and Labs, we follow internationally accepted testing protocols to ensure your results are accurate and reliable. Our soundproof testing rooms eliminate background noise that could affect your responses, making sure the test reflects your true hearing ability.
Key points:
- Measures the softest sounds you can hear at different pitches
- Detects both conductive and sensorineural hearing loss
- Results plotted on an easy-to-read audiogram
- Conducted in a noise-free, controlled environment
- Safe, quick, and entirely non-invasive
Who Needs a PTA Test?
PTA is recommended for anyone who has noticed difficulty in hearing conversations, particularly in noisy environments, or who finds themselves turning up the TV or radio volume more than before. It is also an important screening tool for people who experience tinnitus—a constant ringing, buzzing, or humming in the ears. Children showing signs of speech delay or struggling in school may also need a PTA test, as undiagnosed hearing problems can impact learning and social interaction.
Certain professionals, like airline pilots, call center employees, construction workers, and musicians, are at higher risk for hearing damage due to prolonged noise exposure. Regular hearing checks are essential for them to monitor their auditory health. At Insight Diagnostics and Labs, we also see patients referred by ENT specialists for diagnostic confirmation before treatment, as well as individuals undergoing medical evaluations for occupational or legal purposes. By identifying hearing issues early, we help prevent further deterioration and improve the effectiveness of treatment.
Key points:
- Ideal for people with hearing difficulties or tinnitus
- Essential for children with speech or learning delays
- Important for workers exposed to loud environments
- Useful for ENT referrals and medical assessments
- Supports early detection and treatment of hearing problems
The PTA Test Procedure
Your PTA test begins with a brief consultation where our audiologist will ask about your hearing history, any symptoms you’ve experienced, and relevant medical background. You’ll then be seated in a specially designed soundproof booth to ensure no background noise interferes with the test. You will wear headphones, and in some cases, a bone conduction headband will also be used to measure hearing through different pathways.
The audiologist will play tones of varying pitches and volumes, one ear at a time. Whenever you hear a tone, you signal by pressing a button or raising your hand. The test starts with sounds that are easy to hear and gradually moves to softer ones, pinpointing the exact level at which you can detect sound. In some cases, both air conduction and bone conduction testing are performed to accurately determine the type of hearing loss. The entire process is painless and usually takes about 20–30 minutes. Results are available immediately, and our team explains the audiogram in simple terms, so you fully understand your hearing profile.
Key points:
- Begins with a quick pre-test consultation
- Conducted in a completely soundproof room
- Uses headphones and sometimes bone conduction devices
- Each ear tested separately for accuracy
- Immediate results with full explanation
Benefits of Pure Tone Audiometry
PTA is one of the most trusted and standardized methods for assessing hearing health. The test is safe, painless, and suitable for all age groups, making it a versatile tool for both clinical and occupational purposes. The most significant advantage is early detection—catching hearing loss at an early stage allows for faster and more effective treatment.
For patients considering hearing aids, PTA provides the detailed frequency-specific data necessary for precise fitting. It can also monitor changes in hearing over time, making it valuable for patients with progressive conditions like age-related hearing loss or chronic ear infections. For children, early intervention after PTA testing can dramatically improve language development and educational outcomes.
Key points:
- Early identification of hearing issues.
- Essential for accurate hearing aid fitting
- Monitors changes in hearing over time
- Improves quality of life with timely intervention
- Benefits both children and adults
Preparing for a PTA Test
Preparation for PTA is simple but important for accurate results. Avoid exposure to loud noises for at least 12–24 hours before the test, as this can temporarily affect hearing sensitivity. If you have earwax buildup, it should be removed before your appointment, as it can block sound and lead to inaccurate readings.
Wear comfortable clothing, and try to arrive well-rested, as fatigue can affect concentration during the test. If you’ve had previous hearing tests, bring your records for comparison. Our staff at Insight Diagnostics and Labs will guide you through every step so you can feel confident and relaxed during your session.
Key points:
- Avoid loud noise before testing
- Ensure ears are free of wax buildup
- Get proper rest before the test
- Bring any previous hearing test results
- Wear comfortable clothing for ease
Understanding the Results
The PTA test produces an audiogram, a chart that shows your hearing thresholds for different pitches. The horizontal axis represents frequency (pitch), measured in hertz (Hz), and the vertical axis shows loudness (volume), measured in decibels (dB). The audiogram reveals the softest sounds you can hear at each pitch.
An audiologist uses these results to classify your hearing ability as normal, mild, moderate, severe, or profound loss. This classification helps determine whether you might benefit from hearing aids, medical treatment, or further investigation. Because PTA testing is standardized, results can be compared over time to track any changes in hearing.
Key points:
- Audiogram provides a visual map of your hearing
- Shows both pitch and loudness thresholds
- Classifies hearing loss severity
- Guides treatment or hearing aid recommendations
- Allows tracking of hearing changes over time
