What is the principle for megaphone?
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.
Louder at 800 Hz 50dB or 600 Hz 30dB?
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.
How much louder is 50db then 30db?
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
