Generator Noise Level Simplified: A Buyer’s Guide

Generators provide a vital source of energy for many uses, but their noise levels can be a major concern. When buying a generator, it is important to understand what noise level you’re getting into and how much background noise it will produce in your home or workspace. Taking the mystery out of generator noise levels can help you make an informed decision when purchasing one. Here’s more info on generator noise levels that every buyer should know.

Noise Rating System

Generator manufacturers label their products with decibel (dB) ratings, which indicate the intensity of sound generated by each model. The higher the dB rating, the louder and more disruptive the sound will be. It is important to note that even small increases in dB ratings can make a significant difference in terms of noise output. For instance, an increase from 70dB to 75dB doubles the amount of loudness per se. In addition to dB ratings, manufacturers also list “dBA” numbers on their product labels – this stands for “A-weighted decibels,” and indicates how loud something sounds at equal distances from its source compared to other sources with varying frequencies.

Comparing dB Ratings

When comparing different generators based on their dB ratings, it helps to have some reference points to better understand what kind of sound output they are likely to produce. Some common items and activities along with their corresponding dB rating include:

• Normal conversation – 60dB

• Vacuum cleaner – 72dB

• Hair dryer – 80dB

• Food blender – 88dB

• Garden mower – 90dB

• Chain saw – 110dB

This is just a general guideline, however, as there could be variations depending on various factors such as model specifications and frequency levels produced by specific generators. Furthermore, ambient noises (such as traffic or wind), weather conditions and other environmental elements may also affect perceived sound levels in any given area or environment; therefore, it is necessary to take these externalities into consideration when shopping for a generator too!

Effectiveness Vs Sound Level

The effectiveness of generators largely depends upon their power output capacity—the higher its wattage rate, the more efficient it tends to be—in relation to desired applications such as industrial operations or remote worksites etc., However, this does not necessarily mean that powerful machines are noisier than smaller models; some high-end units offer advanced features like ‘noise dampening enclosures’ that effectively reduce overall sound emission without compromising performance capabilities whatsoever! This makes them ideal for residential settings where background noises should remain relatively low (below 65–70 dBA).

Reducing Generator Noise Levels

Even if you choose a high-performance machine with superior noise reduction features built-in—there are additional measures that you can take in order to minimize emitted sound waves further while your unit is running:

• Use soft rubber mats underneath your machine(s); this helps absorb vibrations & prevent them from reverberating off hard surfaces such as pavements/concrete slabs etc.…

• Place large objects like boxes/crates around your unit(s); they act as natural barriers & prevent amplified echoes within close proximity areas…

• Utilize acoustic blankets specifically designed for muffling engine noises; these panels work best when installed directly onto machines themselves…

• Build custom surrounding walls using dense materials like bricks/wood/insulation boards, etc.; they significantly reduce outside noises & create internal air chambers, thus providing extra protection against external elements…


Buying a generator isn’t always easy but understanding its associated noise level metrics can certainly help simplify the process somewhat! By taking into account all relevant factors mentioned above—including power output capacities versus desired applications along with external environmental influences etc.—you’ll easily find the perfect unit for your needs without breaking the bank either!
