Binaural Beats Cut Morphine Use by Nearly Half in Older Adults After Knee Replacement Surgery

 

Italian researchers ran a careful randomized controlled study with 40 older adults undergoing knee replacement surgery. One group listened to binaural beats (4 Hz) through headphones before their operation, while the control group heard a steady tone. Doctors then objectively measured real morphine use via patient-controlled pumps during the first postoperative day. The binaural beats group consumed just 5.75 mg compared with 11.85 mg in the control group — nearly half as much. Published in a respected peer-reviewed journal from a proper Italian hospital department, this trustworthy evidence suggests gentle sound stimulation may help reduce morphine needs after surgery.
