Summary
This study tested whether playing white or pink noise through headphones before and during a colonoscopy can lower patients' pain and anxiety. 135 adults were randomly assigned to listen to white noise, pink noise, or standard care alone. Researchers measured anxiety and pain using simple visual scales. The goal is to find a safe, drug-free way to make the procedure more comfortable.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- white noise and pink noise delivered via headphones
- What this could lead to
- If it works, this could give doctors a simple, non-drug way to help patients feel less pain and anxiety during colonoscopy.
- What could go wrong
- This is a small, completed trial with 135 people. The effect may be modest or not apply to everyone. Noise might not help those with high anxiety or pain tolerance.
