Ever heard a rhythmic, often 'whooshing' or thumping sound in the ear – a sound that is synchronised with your heartbeat? If so, it is called pulsatile tinnitus, a type of tinnitus that is less common and is said to have various physical causes, such as vascular, or blood vessel, abnormalities, high blood pressure, severe anaemia, or increased intracranial pressure.
Another medical condition that is rarely linked to the 'whooshing' sound is a brain tumour, an abnormal mass of cells in the brain that can be cancerous or noncancerous. Here's what an expert has to say about the link.

What Usually Causes A Whooshing Sound In The Ear?
According to Dr Nikhil C. Hiremath, Consultant Neurologist, Aster CMI Hospital, Bengaluru, the 'whooshing' or pulsating sound in the ear usually happens when you hear your own blood flow. It is often linked to changes in blood vessels near the ear or head.
"When blood flows quickly or unevenly, it can create a rhythm that matches your heartbeat, and the ear picks it up as a sound," he explains. Common reasons include:
- High blood pressure
- Narrowed arteries
- Fluid in the ear
- Middle ear infections
- Increased awareness of normal blood flow when the surrounding area is sensitive
- Stress
- Anaemia
- Thyroid problems
If the sound is constant or disturbing, it is best to get checked by a doctor.
Can Whooshing Sound Be A Sign Of Brain Tumour?
Tinnitus is often harmless, but certain signs can help you know if it needs medical attention.
Dr Hiremath says, "If the ringing or pulsating sound is only in one ear, keeps getting worse, or is always in rhythm with your heartbeat, it could point to an underlying issue."
When tinnitus comes with dizziness, sudden hearing loss, vision problems, weakness, or trouble with balance, it should not be ignored. "A brain tumour is rare, but it can sometimes cause these symptoms along with pressure in the ear or head."
A 2025 study published in the Journal of Neuro-Oncology reports that 3.22 lakh new cases of brain and Central Nervous System (CNS) tumours were estimated in 2022, globally, with the highest incidences seen in Northern America, Eastern Asia, and Western Europe.
Warning Signs That Should Prompt A Doctor's Visit
There are several red-flag symptoms with tinnitus that should make someone see a doctor right away. According to Dr Hiremath, some of the warning signs include:
- If the sound is only in one ear
- If the sound is very loud
- If the sound suddenly appears
“If the tinnitus is linked with ear discharge or bleeding, it needs urgent care,” Dr Hiremath adds. Other serious signs include:
- Loss of balance
- Blurred vision
- Weakness in the face
- Trouble speaking
“If the tinnitus is always in sync with your heartbeat, it may show a blood vessel problem. Strong headaches, pressure in the head, or fainting spells are also red flags. Any of these symptoms should be checked quickly to rule out serious conditions,” the doctor advises.

Tests To Take
To rule out brain-related causes of tinnitus, doctors usually start with a hearing test (audiometry) to see if there is hearing loss. They may also check the ear with an otoscope for blockages or infections. If the sound is pulsating or only in one ear, imaging tests are often advised.
An MRI scan is used to look for brain tumours, nerve problems, or blood vessel changes. A CT scan can show bone or blood vessel issues near the ear. Sometimes doctors order ultrasound or angiography to check blood flow in the head and neck.
Blood tests may be done to look for anaemia, thyroid, or cholesterol problems. These tests help find or rule out serious brain-related conditions.
Conclusion
A whooshing sound may not be serious, but it can be a symptom of an underlying condition, which is why it is crucial to get it checked. Its significance depends on its cause, location, and associated symptoms. A whooshing sound in the ear, known as pulsatile tinnitus, requires medical evaluation to rule out serious conditions like brain tumours and other circulatory issues. Always consult a doctor if you suspect anything serious.
