The set of design and installation measures that minimise sound generated by elevator door operation.
Full Definition
Elevator door noise reduction encompasses acoustic dampening materials, soft-close motor profiles, vibration-isolating door hangers, nylon or polyurethane guide rollers, and sill brush seals. Sources of door noise include panel impact at end-of-travel, hanger wheel rolling noise, belt slap, and resonance in hollow door panels. Modern door operators include programmable deceleration curves that reduce closing impact force. Acoustic panels and mass-loaded vinyl liners are applied to door panel backs in noise-sensitive installations such as hospitals and residential buildings. Compliance with EN 81-70 accessibility requirements also addresses noise comfort for users with hearing impairments.
