Description
Sound-isolating base material Improves leaking of live sounds such as neighboring talks, TV sounds, etc. Adhesive type with high sound leakage.
It can also be used as a construction material for walls, ceilings, plumbing and ducts.
The soft material reduces the occurrence of a symptom(coin sidence effect) that reduces sound insulation performance at certain frequencies.
Radio waves pass through, so you can use wireless LAN and mobile phones.
Precautions for Use:
Depending on the environment of use after installation, there may be a characteristic smell of the product substrates. Open the window and allow for sufficient ventilation.

The volume of noise around your life
Decibels are the most basic "monosashi" when measuring sound size.The larger the number, the louder the sound.
Normally, it is said to be able to live relatively quietly at night and about 50 dB during the day.When the volume is lowered by 10 dB, the human ears can be heard about half the sound.
Depending on how it is transmitted, the sound can be divided into 2 types.
The sound is divided into 2 types: "air sound" that transmits through the air, and "solid sound" that can be heard through the floor or wall.
In general, these sounds exist at the same time, and the method of transmitting is different, so the way of obstruction is different.
It is important to know what sound you want to block from the beginning.
1 in sound insulation, 2 in sound absorption, 3 in acoustic control
In general, sound insulation and sound insulation are used in the same means, and it is thought to be sound insulated.
But in real life this is inconvenient.
By only increasing the sound insulation, the sound will be visible throughout the room, and you will feel physiological pain when you are in such a room for a long time.
Sound insulation for a comfortable home is important to balance sound absorption performance that not only blocks sound but also acts as a cushion for sound.
