How many times louder is an 80 dB sound compared to a 40 dB sound?
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
How much louder is 80dB than 60dB?
80dB is 10 times louder than 70dB. In terms of perceived loudness, an increase of 10dB roughly corresponds to doubling the loudness level.

What is the rms electrical amplitude of this tone in millivolts 80dB and 50mV?
rms - 0.707 times peak 2 peak. since 80dB has no reference there is no answer. dB is mearly a ratio 80dB=10,000 times greater than 0dB dBm is ref to 1 milliwatt and dBu is ref to 0.775 volts RMS if 50mV is p-p then 50mV p-p * 0.707 = 35.35 mV.
How much sound does ear muffs and ear plugs block out?
It really depends on what type you have some products will only block out some of the sound(sound reduction) and others will completely block out the noise. ask some one that have one they could help you.answ2. No ear protectors will block out all noise. Good ones may reduce the sound by more than 40dB, and poor ones should still reduce by better than 20dB.Sounds louder than about 80dB(A) will be damaging to your hearing.Almost all our social interaction is via sounds, and loss of hearing equates to loss of society.
What is the resultant sound level when 70dB sound is added to a 80dB sound?
80.414dB. (If each source has it's own random phasing and are therefore non-coherent)
What distance increase is needed to reduce a sound's intensity from an initial 100dB to a final 80dB?
Sound intensity is inversely proportional to the square of the distancefrom the source.-- Increase the distance from the source by 10 times.-- Sound intensity decreases to 1/102 = 1/100 .-- 10 log ( 1/100 ) = -20 dB-- 100 dB - 20 dB = 80 dB
How loud is hard rock music?
A rock concert in a medium sized club with profesional equipment could go up to 107db. Mind you everything above 80db is extremly harmfull for your ears! 120 db is the painlimit! When you go to a club or concert do not shout in someones ear, you wouldn't do that at home either. Always wear earplugs.
What is the combined effect of two sound levels 80dB and 86dB?
The adding of this two sound will give you total sound level of 87 dBSPL. Scroll down to related links and look at "Adding acoustic levels of sound sources - Combining decibels, adding of levels, or combining levels".
How loud is a motorcycle?
Motorcycles should not exceed 80dB below 35MPH, and 86dB above 35MPH. This may vary between different States. For a more accurate answer you could ask your local State Police station.

What sound intensity will cause permanent hearing damage?
Much depends on the duration that the person is exposed to the sound. Under UK law an employer should provide hearing protection if the average sound level in the workplace exceeds 80db over the course of a day. Peak sound pressure levels should be no more than 135dB.
Where can you find a manual for a Royal Thermo Solutions WS44 weather station?
You can try searching for the manual on the manufacturer's website or contacting their customer support for assistance. Additionally, you may find a digital copy of the manual by searching online on websites that host user manuals and guides.
What can be the reasons of a Call drop?
1. If the network is congested and u are low priority user then ur call might be dropped.2. The signal level for an ideal call isTransmit +43db Receive -60 ~ -80db Some times while receiving call, suppose due to pathloss or shadowing, if ur receiving signal level is -95db, then ur call will be dropeed. During the site survey, Site selection is very much important to avoid the effect of path loss and shadowing. 3. Sometimes there are pockets due to inappropiate radio network planning, in those pockets ur call might be dropped. Appropiate Radio Planning and the adjustment of Antenna's Down Tilt is very much important to resolve this problem.4. During hanover, if the interferrence from the neighbouring BTS is too high the call might be droped. Appropiate Radio Planning and the adjustment of Antenna's Down Tilt is very much important to resolve this problem5. Somtimes SACCH, FACCH signalling channels are not available to provide u a TCH channel. In that case call might be dropped. Repeated SACCH, FACCH can solve this problem.6. Some times it might happen that you are too far from the center of BTS, that is you are at the cell boundary. At that u might face problem to make a call as the transmitted signal from ur MS will not reach BTS. High gain antenna's can solve this problem. there are other different techniques to resolve this problem. But all these solutions varies from vendor to vendor
