The Healthy Geezer: How Dangerous Is the Sound Level of Rock Music? Question: I'm worried about my hearing because I played in a rock band when I was a kid. How dangerous is the sound level on the bandstand? Answer: Sound volume is measured in decibels (dB). You risk hearing loss when you are exposed to sounds at 85 decibels or more. The louder the sound and the longer the exposure, the greater the risk. Here's the bad news: rock music is on many lists as an example of a dangerous sound. Here's one of those lists: 30 dB = library50 dB = rain60 dB = conversation (apolitical)70 dB = vacuum cleaner80 dB = busy street90 dB = shop tools100 dB = chain saw110 dB = rock music among audience120 dB = rock music on bandstand130 dB = jackhammer140 dB = air raid siren150 dB = rock music crescendo If I played electric guitar in the 1960s next to one of those gigundo amplifiers, I'd get to a doctor for an ear exam. But you don't have to be a rocker to suffer from noise-induced hearing loss (NIHL);
anyone at any age can be a victim. About 10 percent of Americans between ages 20 and 69 already may have suffered permanent damage to their hearing from excessive noise. You can sustain NIHL at work, play or sitting around the house. Music players turned up too high can damage your ears. Woodworking can be an unsafe hobby. Leaf-blowers reach hazardous sound levels. Most people's hearing diminishes with age. About 1 in 3 Americans over age 60 suffers from some loss of hearing, which can range from the inability to hear certain voices to deafness. Those who are healthy and not exposed to loud noise can maintain their hearing for many years. The first symptom of NIHL is the inability to pick up high-pitched sounds, or not understanding conversation in a crowd. As hearing declines, you lose the lower-pitched sounds. Prevention is the key to NIHL. Here is some advice to avoid damage to your ears: Avoid exposure to noise when possible. When you can't avoid noise, wear earplugs that are available in drugstores.
Earplugs can stop 25 dB of sound. Cotton in your ears doesn't work. You can cut down noise in the home with rubber mats under appliances and carpets on floors.

What type of oil does a generator use? What should you look for when reading portable generator reviews? What is the average cost of a Stihl chainsaw? Typical portable generators produce noise levels ranging from around 70 dB up to 85 dB, while inverter generators produce lower noise levels ranging from about 50 dB up to about 65 dB. For a larger, whole-house backup system, a Kohler Power Systems 20 kW residential standby generator emits 69 db of noise. Because decibels are measured on a logarithmic scale, a decibel rating that is 10 points higher is twice as loud. For example, a typical vacuum cleaner operates at about 70 dB while an average conversation is about 60 dB. Generator noise levels vary based on their capacity and on what percentage of their capacity they are producing. Even the very quiet Yamaha EF2000iS inverter generator is twice as loud when running at full load as it is when running at 25 percent capacity. The Kohler 20 kW standby generator is twice as loud as the Yamaha EF2000iS, but it produces 10 times as much power.
Both inverter generators and standby generators are designed for low noise output and intended to be used in areas near other people.
