SMALL SIZE - Aquarium Silencer to reduce noise SCIENTIFICALLY PROVEN New invention exclusively at iPetUSA Do you know that your air pump can generate noise up to *0 dB? These noise generated from the mechanical parts in the air pump will be transferred through the air tube which greatly affect the health of your fish! Your fish is at risk from this noise! This newly invented Aquarium Silencer can reduce noise from entering into the aquarium. This device has been tested and scientifically proven from The Poly Tech University of Hong Kong for reduction of water noise generated from air pumps. Aquarium Silencer works in seconds! Silencer simply works by connecting both ends in between the air pump and the air filter. Once the air pump is on, the Aquarium Silencer will immediately filter out most of the noise generated from the air pump. You can actually listen to it too! A simple test can be carried out to prove your silencer is working! (1) Try put your ears on one side of the surface and you can hear the noise generated from the air pump. (2) Install the Aquarium Silencer (3) Put your ear to the aquarium again and you can hear the noise has been significantly reduced! Guaranteed! General Effects of Underwater Noise on Fish Fish use sounds to find food, avoid predators, and choose mates. Since hearing is essential for their survival it is important to understand how they are affected by underwater noise. When marine fish were exposed to sound pressure levels ****0 dB above that in their normal environment (at ******0 Hz) severe problems occurred; the viability of fish eggs was reduced and growth rates for fry were significantly reduced. (Banner and Hyatt, ***3) Shrimp reared under sound levels ****0 dB above ambient noise showed significantly reduced growth and reproductive rates, decreased food uptake and increased mortality. (Lagardere, ***2) The above studies strongly suggest that increased noise levels may seriously impact production levels sought by aquaculture ventures. (Myrberg, ***0)
