Soundproof box for aquarium air pump

In this blog, we will discuss how to soundproof an aquarium air pump. We will provide detailed solutions, processes and strategies that will allow you to make the aquarium air pump soundproof.

There are a few basic strategies you can utilize to address your problem if the air pump in your aquarium is too loud. In most circumstances, the pump will not need to be replaced.

To reduce the noise of an overly loud air pump, use foam cushioning or comparable material. There are several low-cost methods for reducing the pump’s unpleasant noises; however, do not restrict airflow or the pump will overheat.

Fish-keeping may be a gratifying experience whether you like fresh-water tanks or salt-water aquariums. If you have a tiny setup, it might be a cheap pastime, but if you have big plans, it can cost several thousand dollars.

Whatever your aquarist goals are, you’re probably not a fan of the noise an air pump makes. You may quiet the noise and enjoy your aquarium without distractions by performing easy repairs and alterations, depending on the age of the pump.

How to soundproof an aquarium pump?

If you’ve had an older air pump for a while, you may have noticed that it’s become noisier over time. In most cases, you can reduce the racket by doing the following repairs on an old pump:

  • Replace the diaphragm
  • Tighten the screws
  • Replace the air-stones or diffusers
  • Mount on a foam block or padding
  • Insulate the interior compartment
  • Suspend in a jar
  • Place on a cushion or small blanket
  • Build a soundproof box

“Remember always to unplug the air pump before attempting any repair process”

Replace the Diaphragm

Your pump’s rubber diaphragm isn’t built to last. It’s always moving and should be updated once a year. The diaphragm will certainly fail in less than a year if you choose a pump that isn’t built to cope with a huge tank.

Check your pump’s specifications to determine the proper tank size and purchase a diaphragm replacement kit. Make sure to purchase the kit from the same manufacturer as the pump. Each manufacturer’s diaphragm is unique in terms of shape and size.

Tighten the Screws

The vibrations caused by an overused diaphragm might loosen the inside screws that hold the pump compartment together over time. To access the guts of the pump, remove the screws on the outside using a screwdriver.

Sometimes there are only one or two screws in the interior, and if you gently tighten them, the unit’s vibrations will improve.

Tools Required
Screwdriver

Airstone Replacement

Airstones, unlike the pump to which they are linked, are irreparable. Most bubblers aren’t too expensive or difficult to replace, depending on the type and quality.

The pump’s loudness will become louder if the airstones become blocked and useless. You shouldn’t have a problem with a noisy pump if you replace the bubblers every six weeks and maintain the tank clean.

Material Required
airstones

Mounting on Foam 

Foam blocks can assist reduce the noise produced by vibrating air pumps, albeit some are more aesthetically pleasing than others. To accommodate your pump, cut a chunk off of the top of a foam block and two grooves for your air tubing and power wire.

You can use the same type of foam that is used to pack electronics, or you can buy a fitness block like this one. The pump’s vibrations will be absorbed by the PE Foam, which will prevent it from sliding off a table or cabinet.

Foam blocks and cushioning come in a wide variety of sizes and shapes, which can be found both online and at pet stores. Foam aquarium filters can mute your noisy pump while being significantly lighter and less durable.

Material Needed
PE Foam

Insulating the Interior Compartment

The inside compartments of most air pumps, especially the cheaper types, have a lot of wasted space. These open-air zones add to the noise of your pump by increasing vibrations. You can lessen the vibration and sound in the chamber by insulating the hollow sections using Reflective White Foam Insulation.

To access the internal compartment, unscrew the pump first. In the chamber, you’ll notice small, empty areas.

Small pieces of filter fibre can be stuffed into the spaces, but be careful not to cover the diaphragm, cables, or screws. You’ll notice a significant reduction in the pump’s noise once you insulate it and screw it together.

Suspend pump in a Jar

Suspending your pump racket in a jar is one of the strangest and most inventive ways to mute it. Locate a big jar with wide coverage and drop your pump inside.

Suspend the pump in the jar by its legs, making sure they don’t contact the sides or the bottom. You’ll have another acoustic nightmare on your hands if the pump brushes the glass when it’s turned on. Secure the power cord and air tubing at the top of the jar with duct tape. Crimping the tubing or cable is not recommended.

You may easily silence the noise by taping the entire opening of the jar. It’s not supposed to be an airtight seal. Leave a few small spaces near the cord and tubing, or the cord and tubing will get tangled. Here is a video that can show you how to suspend a pump in a jar.

Use a Cushion or towel

Place the pump on a folded towel or small pillow if you’re looking for a simple and cost-effective solution to your pump noise. The most prevalent criticism among aquarium owners is that the pump’s movements generate a rattling noise.

Some people report that the pump vibrates so much that it slips and falls on the floor. The irritating rattle is accentuated when the pump is placed on a wooden table or dresser. The pump is cushioned by the towel, which keeps it from sliding around.

Build a soundproof Box

To create a soundproof air pump box, you’ll need to go a step forward. If you know your way around wood, it’s nothing fancy and no more difficult than the previous method. All you have to do now is follow the steps outlined here.

Required Things

How to make a soundproof box?

  • Make a box out of the plywood. Your external air pump should be one or two sizes larger than the box. This will ensure that your air pump is well-protected. You’ll also need the extra room to fill in the foam for further noise reduction.
  • Make a long, thin slit in the box’s side to allow the water to flow inside. The slot must be located near the top of the box. Comparing it to the air pump’s pipe and then cutting the box is the best technique to assure the perfect slot.
  • Make a slot similar to this in the box’s lid. This opening will be utilised to drain the water.
  • To keep the air pump from overheating within the box, you’ll need to install a fan. The fan should be installed on the opposite side of the first slot. The fan will pull air in via the slots while also removing the hot air created by the air pump.
  • Now that your box is complete, cover it with some generic dynamat. Cover the entire box’s outside and inner walls. The interior position of the lid does not need to be covered.
  • To keep the dynamat in place, use foil tape.
  • Use closed-cell foam for further noise reduction. Cut it to fit inside your box. Wrap the foam in dynamat and tape everything together. Place the foam in the box’s bottom.

Your external air pump’s soundproof box is now ready to use. Put a sound box inside to see how much sound it can capture. If you don’t think the noise catching is enough, add more foam to the sides. Consider adding another fan to help with air circulation in that situation.

Material Needed

How do you make a soundproof box?

  • Take the Measurements. First things first
  • Cut the plywood
  • Make the Ventilation Holes
  • Add the Mass Loaded Vinyl
  • Seal the First Layer
  • Add the Foam Mats – The Second Layer 
  • Assemble the Soundproof Box

How do you soundproof a fish tank pump?

Keep the airline length to a minimum and place the air pump on a vibration-absorbing surface such as foam to decrease the impact of a noisy air pump. It’s also a good idea to play around with where you put the air pump because some surfaces can enhance the noise.

Does a fish tank air pump need to be on all the time?

To keep your fish alive, you’ll need to maintain the filters, heater, lights, and air pumps on practically all of the time. While you can and should switch off your lights, heaters, and even an air pump if you have one, you must keep your filters on 24 hours a day, seven days a week.

Does filter noise bother fish?

Underwater noise has been proven to impact fish behaviour and auditory sensitivity in several studies. All filter noise types muffled the goldfish’s hearing, with the external filter noise (threshold shifts of 15–19dB) having the largest effect at 0.1 and 0.3kHz.

In a fish tank, how long should an air pump run?

According to a recent study, 4 hours of aeration is enough to cope with the surface tension of the fish tank. It is influenced by the tank’s size.
