Soundproof walls to build its
intention is to choose the appropriate sound insulation, sound
insulation, sound insulation and vibration felt felt production
data, with construction science is very important, but consumers
in the purchase of insulation materials when not only to common
sense thinking, some general insulation board for the traveling
sound effect and talent. To simply add data weight and thickness
to travel noise rate, this method is of course useful, but there
are many defects in storage:
1: when the noise volume relatively moving, the noise power is
low, according to the physical rules based panel density doubled
on the sound insulation theory can only add 6 dB, while the
sound insulation wall density increased four times, the highest
amount added 12 db;
2: wall thickness add relatively space of more use to build the
indoor area of relative reduction; (sound deadening felt felt,
Cheng Jing)
3: the wall is thicker, the raw material to produce wallboard
price rise, economic investment increased, add, and relatively
sound harvest is very small.
So, to consider the plan noise factors, the balance of the two
resident arrived in sound insulation, sound insulation, sound
insulation mat letter static Cheng felt professional sound
information is the principle of new sound insulation products,
the sound insulation effect is to add weight and thickness to
the end, and the relative market with the same thickness with
the components of the sound insulation of goods he felt, static,
sound deadening felt not only the noise power is high, the
effect is good, and arrived at the same thickness than other
functions with more excellent heavy goods.
