On the decibel scale an increase of 10 decibels means an intensity increase of times?
10 decibels increase mean measured on a sound pressure level meter. SPL meter. Forget the intensity, because the ear drums and the microphone diaphragms are moved by the sound pressure. 10
Human ear can hear minimum and maximum?
20
What did Pythagoras have to do with music?
Pythagoras discovered the properties of string length, and that certain ratios of string length are more pleasing to the human ear. The ration is 3:2.
Which of the following frequencies can be heard by the human ear -- a. 0.1 Hz b. 10 Hz c. 1000 Hz or d. 100000 Hz?
1000 Hz. The others are outside the range of human hearing. You can feel 10 Hz but not hear it. C. 1,000 Hz
About how many kernels are on an ear of corn?
An ear of corn averages 800 kernels in 16 rows.
What is the lowest decibel of sound that can be heard from a subwoofer by human ears?
A human ear capable of detecting sound at a level of around 12 hz. A decibel is not the correct measurement unit for measuring the human range of sound.
What is the loudest sound a human can hear?
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
How do you measure the sound level of someone talking?
we answer this question by talking which is measured in decibel's and also just use your ear's.
What is the maximum sound level is safe for human ear in DB?
What is the maximum sound level is safe for human ear
What is the softest sound in the world?
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
Will my dog go deaf i used human ear drop in his left ear?
It is not recommended to use ear drops designed for humans on animals, it is much safer to purchase ear drops from a veterinarian as you could do damage.
What is a safe decibel level for a kids game?
You mean the sound pressure level direct at the kids ear, because the level in decibel is dependent on the distanca from the sound source. Go as far as possible from the noise. Nearly "Safe" is a level of 60 dB SPL, but it makes nervous. Learn about decreasing of the Sound pressure. Scroll down to related links and look at "Sound pressure and the inverse distance law 1/r".
How is the noise of a dog barking measured?
The level of a sound is measured by... a Sound LevelMeter. (!) The reading is in dB(A) which is short for the unwieldy "decibels re 20µPa (A)". A 'decibel' on its own doesn't mean anything outside of its algebra - the abbreviation to just "dB" takes the context as read. The pressure is the scale's reference-level and is that of the faintest sound the healthy human ear can detect. The 'A' is a standard weighting toallow for the human ear's non-linear response to frequency. A text-book or on-line reference on acoustics will explain this further and give typical Sound Pressure Levels relevant to human experience.
What is the sound Lovebird makes?
A lovebird has no decibel. The closer your ear is to a sound source the louder it will be. We measure the sound pressure level (SPL) in decibels at a distance. Laymen are happy knowing a fantasy "decibel of 100 dB". But without any distance such value is really nonsense.
What kind of damages can be to the ear with a decibel scale?
some of the damages to the ear are bad. Some are good, and some are ok.We use a decibel scale to find this information out. A decibel scale is a scale that shows you the amount of damage something can do to your ear. An example of a decibel scale would be.....loud music = 120dban infection = 90dbsports = 80dbhole in the ear drum = 100dbblows to the head = 50dbsmall bone problems = 40dbfalls or wax = 30dba jet - airplane = 140db150 is the highest or worst db you can get.And 0 db is the lowest or least worst.0-70 are minor problems.70-150 are major problems caused.
What is the decibel limit of human ear?
im an anonymus,but i read somewhere that about 80 decibels it's dangerous,abouve 100 decibels is painful,and 150 is the limit.not sure,Google it.answer from Romania :D
