Exhaust and intake fans can produce a lot of noise with bigger fans producing an exceptional level of noise. This can make sound coming from the grow area can a tremendous inconvenience when heard throughout one’s household and can even bother close by neighbors. To prevent this from happening, GTA Hydroponics offers soundproofing solutions that you can use in your indoor hydroponic systems.

Reducing noise is possible by using the following.

  1. Insulated Ducting. Regardless of being used for intake or exhaust fans, hydroponic ducts are designed to minimize heat loss and keep condensation down.  To maintain noise at low levels, specially designed acoustic insulated ducting is used.  These types of ducts not only provide sufficient airflow, they also come reinforced with fiberglass that serves to deaden airflow noise. Compared to regular sound absorbers, these are better suited for hydroponic applications.
  2. Neoprene Duct Clamps. Duct clamps are used to connect and secure the duct and fan in a hydroponic grow area.  Neoprene, is a synthetically made rubber much stronger than ordinary rubber. Originally created to be more resistant to oil, its durability extends to heat and chemicals.  When bonded with aluminum, it can be one of the most reliable materials used in duct clamps.  This is perfect not only for ensuring airtight duct connections, but also has a sound barrier effect that reduces fan vibrations and noise.
  3. Duct Silencers. Duct silencers, also known as duct mufflers, also use Neoprene as a foam lining to dampen the noise from air ducts by a significant number of decibels.  This acts as a sound barrier that lessens air turbulence inside the duct, which in turn, produces less noise. These are installed connecting the fan and the duct.  When used together with insulated ducting and neoprene duct clamps, the result is a quieter hydroponic ecosystem.
  1. Room soundproofing. If the three solutions mentioned before are not enough, using sound absorbers or on the walls and the door can further keep the noise to a minimum.  The most common solution is to purchase a sound barrier like those used by music studios.  Some use acoustic foam while others use acoustic panels.
