Analysis of the relationship between material structures and auditoryimpressions

There have been no significant investigations into the effects ofinsulators on auditory impressions. Consequently, in our previous study wecarried, out research on economical and, ecological insulators with layers ofaluminum, waste material and, gray cast iron and established the effects oflayered construction on auditory impressions. In this study, we carried, outfurther research on other economical and, accessible materials that have bettercharacteristics than those previously investigated, and determined theirmaterial characteristics for auditory impressions. We determined the dampingcharacteristics of the insulators using the integrals of their power spectrumsin the vicinity of the power spectrum, peaks. Furthermore, we established, thatthe envelope curve for the impulse response of the insulators had differentmaterial characteristics and conveyed different auditory impressions. ICIC International
