Yes, cockroaches can make noise. The most common noises you might hear won't be their little legs scurrying around inside of your cabinets or walls. Instead, it will likely be a chirping or hissing sound that you hear.
Common cockroaches, such as the American and German species, are not known for making noise. While these pests are sometimes reported to make a clicking sound, this is likely a case of the observer misidentifying click beetles as cockroaches.

True: Why yes, they can. Cockroaches can see humans, and that is why they tend to run in fear when we are in their line of sight. The eye of the cockroach is like a compound lens, made of over 2,000 mini lenses that are photoreceptors and allow them to see in complete darkness.
The answer is that cockroaches do have a sense of smell, and they may be turned off by certain scents, so much so that they may avoid the area entirely. Bay leaves are thought by some to be among the smells roaches hate.
Adult males, adult females, and older nymphs hiss when disturbed or handled. This hiss is very loud and easily heard. This is the only type of hiss produced by females and nymphs. While many insects use sound, the Madagascar hissing cockroach has a unique way of producing its hisses.

At night, cockroaches crawl on humans. They are inclined to seek warm, humid environments. Also, they are fond of the soft tissues of the human body. Thus, if there is a chance for the cockroach to crawl on you, they will most likely do so.
Cockroaches can be a menace, to say the least. However, nothing is worse than cockroaches disturbing your sleep by crawling all over you or your bed. Just the thought of these creatures scampering and crawling on your bed is enough to make anyone's skin crawl.
