ᐅ Fence as noise protection from the neighbor. What materials or designs are most effective at blocking sound?

Hello,

We want to build a fence a few meters away on the neighbor’s property line, mainly to reduce the noise disturbance for our neighbor.

Our neighbor (75 years old) is bothered by the fact that our children (2 and 6 years old) play a lot in the garden, especially now during the holidays and the nearly unbearable heat during the day. They sometimes play outside until just before 8 p.m., as our property is pleasantly shaded from 6 p.m. onwards.

Since the sandbox, pool, and mud kitchen are located close to the property boundary near the neighbor, their terrace is quite close to the activity. Our older child has a hearing impairment and a very sensitive ear, which causes him to speak and shout loudly while playing (which also annoys us), and the younger one naturally raises their volume as well.

So, I had the idea to build a wall on our side in this area to reduce the noise he hears from us. The initial idea was a basement block or formwork block wall, although visually it’s not very appealing and looks more like a silo wall.

Have any of you done something like this before and possibly have suggestions on what absorbs sound best? Whether a solid wooden fence, a dry-stone wall, or a gabion wall… just the required height would be a lot of work with foundations, etc.

Actually, they usually push forward when the waiter arrives, claiming the right of the elder. The younger ones often sneak to the bar with the credit card to get ahead of the others. It’s already turning into a sport.

Our relatives have to be forced to pay for weekend trips and, in return, get unexpectedly invited to an overpriced thank-you dinner. So, exactly the opposite.

To the OP: Is your neighbor aware of your oldest child’s hearing impairment? You can mention special circumstances here.

It’s considerate of you to still think about noise protection—if your relationship with the neighbor isn’t already strained, I’d suggest inviting them over for coffee and explaining that you’re taking on work and costs to protect them, so any contribution would be appreciated. What else can they say besides “no”?

Just because some guides here know an excess of difficult people doesn’t mean your neighbor has to be one of them.

(Doesn’t he have a hearing aid he can adjust?)

Unfortunately, I fear that the effectiveness of such measures is often overestimated when a visually acceptable building height is chosen.

A conversation would definitely be the first step. In the end, it turns out that the neighbor has never really noticed the children because he is partially deaf himself...

Unbelievable^^ 4 pages and only one actual answer to the original question

Regarding the topic and to the thread starter:
When it comes to soundproofing against children’s noise (mostly high frequencies), it’s relatively simple because no particularly complex or heavy constructions are necessary.
Sound propagates fairly linearly (simplified), so it can be blocked or redirected with simple soundproof structures enough for most of it to pass above the neighbor’s hearing level. Let’s leave out the diffracted sound at the overcoming point for now, as that would go too far.

An important factor is the height of the enclosure or barrier, and you should discuss this with your neighbor. Depending on the country, only 1.5m (5 feet) is usually allowed directly on the property line; every additional centimeter must be set back by an additional centimeter from the boundary.

Oops, I misunderstood the issue with the prohibited links... Sorry to the admin.

For clarification: Yesterday, I posted two links to what I believed were neutral informational sources, which were removed by the admin with a warning. My mistake—I misunderstood and thought the rule only applied to advertising, not to all types of links.

For those who still want this information, it was a file called "Sichtschutz_Schallschutz_Praxisleitfaden.pdf," available on the website of the regional government offices of Baden-Württemberg.

Is this acceptable? I couldn’t find a direct rule against it.

The main reason for prohibiting direct links is usually the drop in a website’s own search engine ranking when it refers to many other sites. In contrast, mentioning what to enter in Google & Co is, to my knowledge, generally harmless.
