How are sound levels measured on Noisy Planet?

The app can measure sounds from 0 dBA (sounds so quiet you can barely hear them) to whispering (30 dBA), normal conversation (60-70 dBA), and even a jet taking off (140 dBA). Just remember to turn down the volume, move away from the noise, or wear hearing protectors, especially when the sound level is at or about 85 dBA!

Why does my pool pump make a screeching noise?

Another indicator is the actual sound your pump is making. If it sounds like it’s full of rocks, the source is likely the impeller and housing. If it’s emitting more of a screeching noise, the issue likely lies in the motor. Some like to compare that sound to screaming cats.

How is the sound of a building measured?

If we build up another 10 feet, the building will be 12.5 percent taller, which would seem just slightly taller to us; this is a linear measurement. Using the logarithmic decibel scale, if a sound is 80 decibels, and we add another 10 decibels, the sound will be ten times more intense, and will seem about twice as loud to our ears.

Your car needs to spend the night with your mechanic. Bring him the key in the morning and have him start it up and listen. Like Mark said, shouldn’t be hard to diagnose. Oh check out the car talk “noise emporium” and listen to the loose belt sound, see if it matches up. I agree with the previous posts.

Why does my toilet make a loud noise when I flush?

If you notice your toilet making a loud noise, either when flushed or randomly, it’s a clear indicator that something is wrong with your toilet. The problem is most likely a loose washer in the ballcock assembly, which is common among older toilets with a metal ballcock-style fill valve.

Why is my SSD making a weird noise?

A SSD has no moving parts, and does not create any significant amount of electro-static “noise”. I presume that the HP designers of the computer would have addressed any such possibility. So, it’s more likely to be the cooling-fan that speeds-up when the CPU is working “hard” (and producing more heat than when the CPU is “idle”).
