There are several noise problems for those who live in an apartment. In this video we talk about the most common noises and explain the acoustic materials we use for each case.
If you have any questions, please send your question here in the comments and we'll answer.
00:00 Introduction
00:18 Types of noise
- There are two main types of noise, airborne noise and structure-borne noise.
Airborne noise is easier to solve, it is such noises as television, conversations, barks and all noises that goes thru open windows or thin walls.
The structure-borne noise can result from an impact on a solid surface or a low-frequency sound vibrating a solid surface. Examples of this type of noise are drilling machine, falling objects, draging the furniture and slamming doors and drawers.
01:35 Doorway
- In many cases, the apartment entry door is very simple and thin, causing airborne noise to bother much more than they should. Replace the door for an acoustic door will decrease the transmission of noise into the apartment (and also the noise from inside to the hall). All doors have guillotine at the bottom, a system that, when closing the door, makes a rubber descend through the width of the door, capping the gap between the door and the floor - useful also for not passing wind and insects!
02:32 Window
- The most common noise is the noise coming from the window. Traffic noise, loud talk and children playing on playground are good examples of what may be bothering you. Placing an acoustic window is almost a magical solution. It isolates about 80% of the external noise.
03:13 Walls and ceiling
- Drywall today, drywall tomorrow, drywall forever! But it's not any kind of drywall, it needs to be with at least two drywalls and wool plates between the plates. This ensures very good insulation. The drywall is 8 cm thick (~3 in) and can have the texture finish, paint, wallpaper, or even acoustic foam, uniting insulation with absorption.
05:00 Floor
- A good solution for the noise coming from below is the installation of an acoustic floor, it's composed by rubbers that soften the transmission of vibration (structure-borne noise). Thick mats or even loose rubber plates are also useful.
