2. Different Kinds of sounds in odia
Sound is a mechanical vibration which travels through an elastic medium, as a variation in
the pressure exerted on the particles which comprise it Hewitt, 2015. Sound can be
perceived as pleasant or unpleasant, although the boundary that separates music and noise
can be very thin and subjective. Most unpleasant sounds are several noise types, and,
despite some elements and preferences, pleasant sounds are frequently related to music
Hewitt, 2015. However, the task of differentiating different types of music from noise
becomes a question of esthetics, outside the scope of this document.
Normally, noise traffic and factory noises is linked to unpleasant sounds; nonetheless,
sometimes it is not directly associated with them white noise or background noise, i.e.,
ambient sound; McDermott, 2012. On the other hand, music is associated with pleasant
sounds frequently music types as classical, relaxing, or sedative although they are
conditioned by preferences and familiarity McDermott, 2012 or the listener’s cultural
association McDermott et al., 2016. Regarding sound effects, research has shown sound
produces effects on human health, in both physically and psychologically Cowan, 2016.
