Why ten to the power minus twelve is the standard intensity of sound?
That value is the threshold of hearing.
How many hours is 8mb?
How many hours of what? If you are referring to music or sound files, a typical value is 1 MB per minute, although this can vary a lot, depending on the sound quality.
Give a possible value in decibels for the sound level detected from two people having a normal conversation at a distance of 1 meter?
53dB
What is the R value of attic insulation covered with plywood decking?
Every insulation has a different R value. It ultimately is determined by which insulation you will be using. Now lets do rough estimate. 4" thick, regular fiberglass mat has R-value of 13. Assuming that plywood has the same to half the insulating value of fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that 4" mat. Roughly R-1.6 to R-0.8
Why do sounds get quieter the further away you are from the source?
Louder or fainter means more intense or less intense of sound vibrations respectively.Intensity in turn is the energy per unit area.Imagine the source of sound to be at the centre of a sphere. When you are far away then the radius of the sphere would be larger and thus the surface area of the sphere also becomes larger.As the energy given out by the source of sound is divided by larger area to get the intensity its value becomes lesser. Hence fainter.Ear drums and microphone diaphragms are moved by sound pressure.Note: Sound power (sound intensity) is the cause - and the sound pressure is the effect. The effect is of particular interest to the sound engineer.Another Perspective:The intensity (loudness) of sound decreases with the square of the distance from the source.
What is a good value for dB attenuation?
A good value for dB attenuation depends on the specific application. In general, higher dB attenuation values indicate better noise reduction or signal loss. For example, a dB attenuation value of 20-30 dB is commonly seen in noise-canceling headphones, while 40-60 dB attenuation is typical for industrial ear protection.
What is the equation for self attenuation in radiochemistry?
The equation for the attenuation of a gamma-ray flux passing through a path of length x in a sample with linear attenuation coefficient u can be expressed as I = I0 e ^-u*x. For most environments, the value of u is not known and must be estimated by measurements.
Why higher value of roll of is disirable for a filter?
The higher the rate or roll-off, the higher the out of band attenuation.
Why higher value of roll off is disirable for a filter?
The higher the rate or roll-off, the higher the out of band attenuation.
What is the value of a Indiana pacers blanket?
20-45 USD
What is the insulation or r value of water 2 feet thick?
What is the r value of water 2 feet thick
What is the acoustic value (desible gained ) by increasing the mass of gypsum board?
You may expect an increase in noise attenuation of about 3dB for each doubling of the mass of your gypsum board. Using boards of different thickness on opposite faces of the wall will further increase the sound loss.
What is the value of a blanket from World War 2?
About twenty-five dollars. It's not much so i would personnaly hold on to it. I still have my dads 1943 blanket.
What is rising action of the story of THE BLANKET?
The rising action in the story "The Blanket" involves the protagonist's journey to finding a special blanket that holds sentimental value. As they encounter challenges and obstacles along the way, the tension builds as they get closer to their goal. The rising action sets the stage for the climax where the resolution and meaning of the blanket are revealed.
What is the best way to measure sound?
The best way to measure sound is by using a sound level meter. This device measures the intensity of sound in decibels (dB) and provides an accurate representation of the sound pressure levels in the environment. Sound level meters are commonly used in various industries to assess noise levels and ensure compliance with safety regulations.
How much is a yard of silver wirer?
Do you mean what is its value? How thick is the wire?
What is a Penny worth Prior to the year 1942?
There is no blanket value. Prices range between 10 cents and hundreds of dollars. For a specific value, ask about a specific coin.
