Why does Suzhou Electronics Factory have electrical audiometry in its physical examination? I haven't heard of anywhere else.

Enterprises are obliged to do "occupational health examination" for employees before, during and after their posts, which is not a general physical examination.

Workers who are exposed to any harmful factors at work must undergo occupational health examination of related projects.

Contact noise is electrical audiometry to check whether there are symptoms such as noise deafness and hearing loss.

In addition, common dust-exposed people must undergo chest X-ray examination.
