When it comes to home appliances like vacuum cleaners, noise level can be a crucial factor to consider. Especially if you have neighbors or family members who are sensitive to loud noises, it’s important to choose a vacuum cleaner with a low decibel (db) rating. But what exactly does the db rating mean, and how much louder is a 60 db vacuum cleaner compared to a 20 db whisper?
What is the db rating?
The db rating, or sound pressure level, is a measure of the intensity of sound relative to the quietest sound that can be detected by the human ear. The scale is logarithmic, meaning that each increase of 10 db represents a tenfold increase in the sound intensity. For example, a sound that measures 50 db is ten times louder than a sound that measures 40 db.
How loud is a 60 db vacuum cleaner?
A vacuum cleaner with a 60 db rating is considered to be moderately loud. It is slightly louder than a normal conversation, which typically measures around 50-55 db. A 60 db vacuum cleaner is also louder than a dishwasher (45-50 db), a fan (35-45 db), and a refrigerator (35-40 db).
How quiet is a 20 db whisper?
A whisper typically measures around 20-25 db. A 20 db whisper is extremely quiet, and it may be difficult to hear if there is any other noise in the room. In fact, a 20 db whisper is quieter than a rustling leaf (25 db), a ticking watch (30 db), and even the sound of breathing (10-20 db).
How much louder is a 60 db vacuum cleaner compared to a 20 db whisper?
To calculate the difference in sound intensity between a 60 db vacuum cleaner and a 20 db whisper, we can use the formula:
Sound intensity difference = 10^(difference in db/10)
So, the difference in sound intensity between a 60 db vacuum cleaner and a 20 db whisper is:
Sound intensity difference = 10^((60-20)/10) = 10^4 = 10,000
This means that a 60 db vacuum cleaner is 10,000 times louder than a 20 db whisper. That’s a huge difference in sound intensity, and it highlights the importance of choosing a quiet vacuum cleaner if you want to avoid disturbing your family, your neighbors, or your pets.
How to choose a quiet vacuum cleaner?
To choose a vacuum cleaner with a low decibel rating, look for models that are specifically designed to be quiet. These may have features like insulated motors or noise-reducing exhaust systems that help to reduce the overall noise level. You can also look for vacuum cleaners that have a db rating of 60 or lower, or read reviews from other customers to see how quiet a particular model is in real-world use.
Some popular vacuum cleaners that are known for being quiet include the Shark Navigator Lift-Away NV356E, the Miele Complete C3, and the Dyson V11 Absolute. These models all have db ratings of 60 or lower, and they have received high marks from customers for their quiet operation.
Conclusion
When it comes to choosing a vacuum cleaner, noise level is an important factor to consider. A 60 db vacuum cleaner is moderately loud, while a 20 db whisper is extremely quiet. The difference in sound intensity between the two is 10,000 times, highlighting the importance of choosing a quiet vacuum cleaner if you want to avoid disturbing others. By looking for models with a low db rating or features that reduce noise, you can find a vacuum cleaner that works well and operates quietly.

Frequently Asked Questions
What does decibel (dB) mean?
Decibel (dB) is a unit used to measure the intensity of sound or noise. It is a logarithmic scale, with a doubling of decibel level corresponding to a tenfold increase in sound intensity.
How much louder is a 60 dB vacuum cleaner compared to a 20 dB whisper?
A 60 dB vacuum cleaner is 64 times louder than a 20 dB whisper. This is because an increase of 10 dB corresponds to a tenfold increase in sound intensity, so an increase of 40 dB corresponds to a tenfold increase in intensity four times over (10 dB + 10 dB + 10 dB + 10 dB = 40 dB), which is 2 x 2 x 2 x 2 = 16 times over, and adding another 20 dB to that gives 16 x 4 = 64 times over.
Is 60 dB loud enough to damage hearing?
Prolonged exposure to sounds at or above 85 dB can cause hearing loss. However, it is unlikely that a vacuum cleaner operating at 60 dB would cause hearing damage, as this is below the level that is generally considered harmful.
What is the average decibel level for everyday sounds?
Some common decibel levels for everyday sounds include: normal conversation (60 dB), busy street traffic (80 dB), lawn mower (90 dB), rock concert (110 dB), and thunderclap (120 dB). It is important to note that exposure to sounds above 85 dB can cause hearing damage over time.
