Reducing Noise on a Portable Generator

Portable generators are useful when a power outage strikes. Generators also come in handy during an emergency, but their constant noise can sometimes annoy and endanger your health. Studies claim that loud, sustained sound can make concentration impossible, affect your sleep, and increase the risk of heart-related illnesses.

Vibration and the exhaust system are the two sources of noise in a generator. However, creating an enclosure around the exhaust system can allow a generator to breathe, make it more efficient, and restrict its annoying noise. Besides generator repair, these are a few other proven ways that can help reduce noise from a portable generator.

Install Exhaust

Experts recommend exchanging a generator exhaust with a motorcycle exhaust. A motorcycle exhaust can be found at a local motorcycle custom shop near you at an affordable price. Alternatively, create a custom exhaust and attach it vertically to the generator to reduce noise.

Create an Enclosure

Creating an enclosure around the engine can as well help lower the noise from a generator. The generator should sit in the middle of three walls, with the connections and switches installed on the open side for accessibility. Given that cinder blocks come with a natural seal, they are the perfect material for generator walls. Your cinder block should be stacked to a taller height than the generator. But leave a 6-inch breathing space between the wall and generator for efficiency. Take time inside the house to test how noisy your generator is after surrounding it with cinder blocks. If the results are not satisfactory, seal or add a little insulation to the walls to see if the noise will reduce further.

Fit the Engine House with Anti-Vibration

Adding a vibration and sound dampening material to the generator house can help reduce motor noise. Stock crews are fitted with rubber gaskets that aid in noise reduction. However, generator users can add longer bolts and rubber washers to improve their results. Look around the frame of the generator to see where the stock screws secure the rubber gaskets. Then attach the rubber washer here to help reduce noise and vibration. However, it may be necessary to replace the stock bolt with a new screw and add rubber gasket on top of the metal washer to sandwich the frame between the anti-vibration rubbers.

A quiet portable power generator has never been a simple device to come across. Instead, generators are powerful equipment that has to make noise to generate power. But some generators create lower noise due to their size. Though some generators are tranquil enough, conversing with a friend near them can be hard. The sound around portable generators running on gas-powered engines can be loud. But you can add anti-vibration materials to a generator or move it from the vicinity to try to reduce the level of its annoying noise.

You can use either absorption or reflection material to minimize the noise that a gas-powered generator creates. Just open up the casing of the generator and attach the absorbent material to the engine housing or inside the casing. But note that the generator can sometimes get hot and require extra space inside the house or casing for cooling and air circulation.
