ᐅ Is this sufficient as sound insulation according to DIN 4109 in a single-family house?

Hello everyone,
In the scope of work description from a potential home builder, it states that basic sound insulation according to DIN 4109 will be installed.
Google says that this is the legal minimum requirement and not really impressive. The question is whether this is actually sufficient in practice? We are planning a 140 m² (1507 sq ft) city villa with currently one small child.
How should this be worded in the scope of work if we want better sound insulation? Are there "better" DIN standards? Do construction companies even offer this, or are they already fixed by their building methods (in this case, lightweight expanded clay aggregate from prefabricated elements)?
Thank you very much!

I just joined the Homeowners’ Protection Association and would hire a consultant from there.They can also review the contract for you, if you wish.
Inspections are at least as important as the contract. Unfortunately, anyone can call themselves a construction supervisor. Similar to real estate agents, there is a lot of malpractice in this area.
It is better to hire a sworn expert and have each trade inspected and approved.

Thanks first of all for your input.
We got in touch with the construction supervisor because he is "located on the property." He is also connected to the home building company that has already built many houses with him there. Until now, we didn’t even know that construction supervisors exist. We still don’t fully understand everything he does. In any case, he would always be involved.
Regardless, we will hire an expert through the building owners’ protection association. The construction supervisor seems trustworthy and is well established in the area, but he is not independent. I hope he won’t be put off by us also bringing in an expert to work alongside him, but we definitely want to have this expert.
I will have the building owners’ protection association review the construction performance specification and see what they say about sound insulation.

Mottenhausen6 Nov 2018 14:23Which type of sound insulation is more important to you: (1) from outside the house, or (2) inside the house?
1. The first usually takes care of itself in typical residential areas with windows that comply with current energy-saving regulations. Otherwise, if there is a higher need, build solid walls using Poroton or sand-lime bricks (and external thermal insulation composite systems).
2. The second mainly depends on habits and individual factors. For example, a house with poor sound insulation can still be quiet, and vice versa: Where is the washing machine located (ground floor/upper floor)? How loud is the dishwasher? Are the TV’s internal speakers or a 1000 W sound system used? Are there sound-absorbing furnishings, staggered or matching work and sleep schedules, and so on?
By the way: even the best sound insulation can’t replace reasonable child upbringing. Some people might even appreciate hearing if things are getting a bit noisy in the children’s rooms or if the shower is finally free. Don’t get me wrong, I also prefer a quiet home…

1. The first type is usually resolved by itself in typical residential areas with windows that comply with current energy-saving regulations. Otherwise, build solidly using Poroton or calcium silicate bricks (and external thermal insulation composite systems) if there is a higher requirement here.Don’t overlook that the insulation of even the best bricks or windows can be compromised by a decentralized ventilation system.

Even the best soundproofing can’t replace good parenting. Some might even appreciate hearing if things are getting a bit lively in the children's rooms. When it gets too lively here (especially the wall/furniture), there’s usually nothing to hear at that moment. Dangerous silence and all that 😀Similar topics
