Low-frequency hearing test: what to know

Low-frequency sounds are deeper tones, such as a low voice or rumble. During audiometry, you usually listen through headphones and signal whenever you hear a tone. The clinician records the quietest sounds you detect at different pitches. A low-frequency change may affect the fullness or quality of sound rather than making every conversation equally difficult. Earwax buildup can block sound, while inner-ear conditions such as Meniere's Disease can affect hearing along with pressure, ringing, or dizziness.

Tell the audiologist when the change began, whether one or both ears are affected, and whether you notice tinnitus, dizziness, ear pressure, discharge, pain, or recent loud-noise exposure. Avoid inserting cotton buds or objects into the ear. Bring details of medicines and previous hearing results. The test is generally non-invasive; follow-up may include looking in the ear, repeating measurements, or referral depending on the pattern.

Arrange urgent medical assessment for sudden hearing loss, especially in one ear, or hearing change with severe dizziness, facial weakness, severe headache, or neurological symptoms. Seek prompt advice for ear pain with discharge, injury, or a blocked sensation that persists. Do not delay evaluation by assuming a new change is only wax.

Ask which frequencies changed, whether the result suggests blockage or inner-ear involvement, whether the other ear should be tested, and what follow-up is needed. Ask when to repeat the test and which symptoms should trigger earlier review.
