Technical FAQs & Helpful Content

FAQ Test d'Audition Haute Fréquence

Tudo o que você precisa saber sobre este instrumento de diagnóstico, procedimentos de calibração e normas técnicas.

01.What is the normal high-frequency upper limit of human hearing?

Healthy human hearing in young adults ranges from 20Hz to 20,000Hz (20kHz). As people age, natural high-frequency loss (presbycusis) gradually reduces upper hearing limits to 12kHz–16kHz.

02.How does the High-Frequency Hearing Test work?

The test plays calibrated high-frequency sine waves starting at 8,000Hz (8kHz) and climbing step-by-step up to 20,000Hz (20kHz). Listen at quiet, comfortable volume levels and note the highest frequency tone you can perceive.

03.Why can't I hear frequencies above 15,000 Hz during the test?

Inability to hear extreme high frequencies can be caused by natural age-related hearing decline, prolonged loud noise exposure, or hardware limitations of budget headphones and laptop speakers.

04.Can budget laptop speakers or cheap earbuds reproduce 18kHz to 20kHz tones?

No. Small laptop micro-speakers and budget earbuds experience severe high-frequency roll-off above 14kHz–16kHz. High-quality studio headphones or calibrated IEMs are recommended for accurate testing.

05.What is presbycusis and at what age does high-frequency hearing decline?

Presbycusis is age-related sensory hair cell loss in the cochlea. High-frequency perception typically begins declining gradually after age 20 to 25.

06.What volume level should I set during a high-frequency hearing test?

Set your system volume to a comfortable, moderate level using a standard speech or 1kHz reference tone. Never increase volume to force hearing ultra-high frequencies, as excessive volume can damage hearing.

07.What is tinnitus and does it affect high-frequency hearing tests?

Tinnitus is a condition causing ringing or buzzing sensations in the ears. High-pitched tinnitus can overlap with 8kHz–12kHz test tones, making detection harder.

08.What is the difference between an online hearing screener and a clinical audiogram?

An online test is an informal educational screening tool. A clinical audiogram is performed by an audiologist in a soundproof booth using calibrated bone-conduction transducers.

09.How can I protect my high-frequency hearing from noise-induced hearing loss (NIHL)?

Use high-attenuation earplugs at loud concerts, keep headphone listening volume below 60% of maximum, and take frequent quiet breaks during long listening sessions.

10.Why do high-frequency sine waves sound like faint static or clicks at high pitch?

When sine waves reach your personal hearing ceiling or driver playback limits, you may hear mechanical transducer click artifacts rather than a continuous tonal pitch.
