What can be used to reduce noise during door operation?

Using sound-absorbing panels is an effective method for reducing noise during door operation. These panels are specifically designed to absorb sound waves, minimizing reverberation and transmission of noise. By installing them around the elevator entrance or on adjacent walls, the overall noise produced during door operation can be significantly decreased, creating a quieter environment.

Thicker door materials can also contribute to noise reduction, as denser materials tend to block sound more effectively than thinner ones. However, the primary function of sound-absorbing panels is to directly address sound control by absorbing it rather than just blocking it.

Rubber seals around the frame are beneficial in reducing drafts and preventing air leaks, but their primary purpose is not to absorb sound. While they may provide some sound insulation, their effectiveness is less than that of dedicated sound-absorbing solutions.

Paint with soundproofing properties is not as widely recognized or effective in reducing noise during door operation compared to more direct solutions like sound-absorbing panels. While there are specialized paints that may help to an extent, they generally do not have as significant an impact on noise levels as physical sound-dampening materials. Overall, sound-absorbing panels are the most effective and targeted choice for reducing noise in this context.
