Basics of Soundproofing
First, let’s check these places.
The measures we take differ greatly depending on the case.
- Where do you hear the sound coming from?
- What kind of sound is it? Is it a voice or a vibrating sound?
- Is it from inside the building or from outside?
- Is your room structured within an apartment, or detached house?
- It is on the 1st floor? Is it upstairs?
- Is the sound coming from the side? from above? from below?
- Do you want to block the sound that you hear or reduce the sound that you make?
The basics of soundproofing comes down to "gaps"
No matter how good the fittings or soundproof products are, if the sound is able to come in from somewhere, the effect will be halved, and it will be completely ineffective. (Gaps between doors and windows, ventilation fans, and vents, as well as gaps due to warping of buildings, etc.) It depends on whether you can hear sounds due to a lot of gaps, or whether the walls and floor are thin and resonate. First let’s close the gaps up.
Let’s think about the type of furniture and where to put it
- Use curtains rather than blinds to prevent the echoing of room sounds
- Replace hardwood flooring with something softer such as carpet
- Place sound-producing objects such as TVs and speakers as far away from the wall as possible.
If you are concerned about the sound from below,
- change from a futon to a bed
- change from a low table to a regular table
Just by creating distance from the places that you hear sound, you will find yourself surprisingly less bothered.
Understand "sound absorption" and "sound insulation"
For soundproofing, combining "sound absorption" and "sound insulation" greatly enhances the soundproofing effect.
- What is "sound absorption"?
- It is the function of absorbing the generated sound and not reflecting it back. On the other hand, if the sound passes through to the outside, the sound will end up being transmitted to the outside.
- What is "sound insulation"?
- What is "sound insulation"? It is the function of bouncing and reflecting the sound. On the other hand, if the sound does not pass through to the outside, the sound will echo inside.
Since sound absorption and sound insulation have different properties, we recommend that you consider using both of them together when soundproofing.
