Descriptive Acoustics for Music and Speech Students

Speech and Music: Acoustics, Signals and the Relation between Them

The codings of speech and music are different and in some ways complementary. The voice operates on acoustical principles distinctly different from those of (other) musical instruments. This paper explains how and poses the question: are the different codings the result of the different acoustics, or vice versa? What if the instruments came first? This paper develops the conjecture that the pit...

Acoustics for Amplified Music and a New, Variable Acoustics Technology

Surveys among professional musicians and sound engineers reveal that a long reverberation time at low frequencies in halls during concerts of reinforced music is a common cause for an unacceptable sounding event. Midand high-frequency sound is seldom a reason for lack of clarity and definition due to a up to 6 times higher absorption by audience compared to low frequencies, and a higher directi...

Effect of classroom acoustics on the speech intelligibility of students.

PURPOSE To analyze the acoustic parameters of classrooms and the relationship among equivalent sound pressure level (Leq), reverberation time (T₃₀), the Speech Transmission Index (STI), and the performance of students in speech intelligibility testing. METHODS A cross-sectional descriptive study, which analyzed the acoustic performance of 18 classrooms in 9 public schools in Belo Horizonte, M...
