First of all, I think this is a very good question, seeing as most people naturally tend to believe that the only use for fences is for safety, privacy, and security. And even though fences are great for security and privacy, their benefits go beyond these use cases alone.
For instance, one of the lesser-known benefits of fencing is to reduce noise. During my time in Fencing Kent, most of the demand came from areas with huge noise and customers looking for noise reduction solutions. Fencing may not necessarily jump into the mind as the most appropriate solution for this, but it is actually quite underrated in this regard.
Naturally, an important consideration when building a fence with noise reduction in mind is to make use of appropriate materials. I would also recommend talking to a fencing expert seeing as these are the people with extensive knowledge about fencing and particularly noise reduction through appropriate fencing materials.
