What are the objective of limitation sight and hearing?

The objectives of limiting sight and hearing are to:

* Protect people from harmful stimuli. Loud noises and bright lights can damage the ears and eyes, respectively. By limiting exposure to these stimuli, we can help to preserve these important senses.

* Improve concentration. When we are distracted by sights and sounds, it can be difficult to focus on what we are doing. By limiting these distractions, we can improve our concentration and productivity.

* Create a more relaxing environment. A quiet and dimly lit environment can be more relaxing than a noisy and brightly lit one. By limiting sight and hearing, we can create a more peaceful and restful atmosphere.

* Enhance privacy. When we are able to control what we see and hear, we can better protect our privacy. By limiting sight and hearing, we can make it more difficult for others to observe or eavesdrop on us.

In some cases, it may also be necessary to limit sight and hearing for safety reasons. For example, in a hazardous work environment, it may be necessary to wear earplugs or goggles to protect the ears and eyes from injury.
