This is an implementation of the calculation of STC value according to ASTM E 413-04. Classification for Rating Sound Insulation.Input the transmission loss in one third octave bands (dB) and enter the frequency bands and the program will calculate the STC value and produce a graph.The center...

the stationary signal f(t)=cos(2*pi*5*t)+ cos(2*pi*10*t)+ cos(2*pi*20*t)+ cos(2*pi*50*t)having frequencies of 5,10, 20and 50 Hz at any given time instant.MATLAB program can be implemented to plot the stationary signal mentioned above:Clear...

PCSA is a frequency domain analysis technique that can be used to transform PSDs (as those in a spectrogram) to the form of a two-dimensional histogram with frequency-magnitude bins. PCSA can be used to examine the spectral characteristics of a long period of data. It summarizes magnitudes and...

Function HISTF ('flexible histogram') extends Matlab's HIST by letting one bound displayed percentiles, set x-axis limits and y-axis maximum, set x bin size, and draw a marker line at given x position. In contrast to HIST, relative rather than absolute frequencies are displayed. (Note: when range...
