a dB (a decibel) measures power ratio. A power ratio of n is 10 log10 (n) dB. So 50dB represents a power ratio of 105.
It is an "onomatopoeic" ("onomatopoeia" = the formation of a word from a sound associated with what is named) name. When you walk in them the sound like "flip" "flop".
Something that sounds like the word that represents it. For instance flip flops are an onomatopoeia because when you walk in them they make a sound that sounds like flip flop.
Sound of electricity
if i made ear defenders i would : Use foam because - it will absorb the sound Use rubber because - it has a lot of air bubbles in it. Sound takes a long time to travel through gases like air . Also some of the sound may reflect off the rubber. airpoo Vacuums, because sound travels best through air and there would be no air to travel through. And use cotton wool. : )
The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end. The megaphone increases the volume of sound by increasing the acoustic impedance seen by the vocal cords, matching the impedance of the vocal cords to the air, so that more sound power is radiated. It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because the frequency response of the megaphone is greater at higher sound frequencies.
Sound Pressure Level(dB SPL) response , based on Equal- Loudness contours( ISO 226:2003 rev) and the Original ISO Std( set for 40 phons), applied in correlation to Fletcher Edmund - for Psychoacoustics, show that 30 dB @ 600Hz in quieter than 50dB @ 800Hz. ( 3rd Octave diagram range 10Hz to 20 KHz.) . FFT /sound density and 3rd Octave are in line for this particular case.
The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity

You don't need 100% hearing. You must be able to clearly hear with both ears and your back turned towards the source, a regular conversational voice in a quiet room from a distance of 6ft.If your medical examiner decides to perform an audiometric speech discrimination test you must pass with scores better than:Your better ear at sound levels 500Hz, 1000Hz, 2000Hz, 3000Hz with 35dB, 30dB, 30dB, 40dB respectively.Your worst ear at sounds levels 500Hz, 1000Hz, 2000Hz, 3000Hz with 35dB, 50dB, 50dB, 60dB respectively.
they sound like a bird
it might sound like fawn.
