The stethoscope effect is a common issue in in-ear headphones, where the earplug wire or unit experiences external collisions or air friction. The resulting vibration passes directly through the earplug wire (which is generally stiffer, aiding in vibration conduction) into the ear canal, creating an unpleasant sound.
How to Solve the Stethoscope Effect:
Since the stethoscope effect arises from the shaking and friction of the earplug wire, several solutions can be implemented:
Reduce Cable Length: Shorten the distance between the player and the earplugs by placing the player in a chest pocket, minimizing earplug cable movement.
Internal Cable Placement: Place the earplug wire inside clothing; the pressure from the clothes prevents wire movement, eliminating the stethoscope effect.
Secure Terminal: Fix the terminal of the earplug cable to ensure stability and prevent wire movement, consequently eliminating the stethoscope effect.
Tie a Knot: Tie a knot at the end of the earplug cable; a tighter knot reduces the visibility of the stethoscope effect.
Around-the-Ear Placement: Position the earplug wire around the ear, reducing the stethoscope effect significantly.
Pull Wire Up from the Back: Lift the earplug wire from the back, providing stability and reducing movement, while also concealing the earplugs effectively.
The stethoscope effect is a common occurrence in in-ear headphones, although its severity varies between different headphone models. Bluetooth wireless headphones and other earplugs employ various methods to mitigate the stethoscope effect. Experiment with the suggested solutions above to enhance the overall earphone experience and minimize the impact of the stethoscope effect.
