Octave band sound levels provide the sound at each frequency, but how then can dBA be calculated from the octave band sound values in dB? It’s a common question for Todd Beiler, acoustical engineer at CENSEO AV+Acoustics. The answer to the question is yes; dBA can be determined from octave band sound levels [...]
It’s unlikely that you’ve poured over coffee bean acoustics as you sip a latte, but for Preston S. Wilson, underwater acoustics associate professor at The University of Texas, exploring the sounds emitted by coffee beans roasting was a matter of sound engineering, great curiosity, and the eventual discovery of an increasingly sustainable solution [...]
Vocal learning has been a subject of research in the fields of acoustics and social science for many years. Over time, findings have proven positive in some types of birds, bats, and cetaceans including whales and dolphins. Research by avian scientists has identified specific neural pathways in the brains of songbirds, allowing for a [...]
