Assuming that the 3 dB frequency is inversely proportional to the baffle diameter I have arrived at the following approximation for calculating the -3dB frequency as a function of baffle diameter. f(3) = 115/W(B) (where W(B) is …

At higher frequencies that see the baffle as sufficiently acoustically large, you end up with a 6 dB increase in output. At lower frequencies as you go …

Introduction. The so called 'baffle step' is an increase in output from a loudspeaker as the size of the baffle becomes significant in terms of the wavelength of sound for a range of frequencies. At low frequencies, where the baffle (the panel the loudspeaker is mounted on) is small compared to the wavelength, the speaker is assumed to be operating with a spherical radiation pattern.

Calculate Baffle Diffraction Loss. Understanding Baffle Step and Diffraction Video. At high frequencies, a loudspeaker radiates sound directly forwards. At low frequencies, the sound "leaks" around the sides and rear of the enclosure, and becomes omnidirectional. This transition manifests itself as a loss of output on the forward axis at low frequencies, and in an anechoic …
