What are the components of acoustics?

The basic components of a sound wave are frequency, wavelength and amplitude .

What are the general principles of acoustics?

No. 1 of the governing principles of acoustics is the Mass Law . Essentially one of the most effective ways in enhancing acoustic performance on a facade is to increase the mass or weight of its main surface components. Going by the Mass Law, for every doubling of weight of a material, it equates to a 6dB improvement.

What are the basic elements of sound?

Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration , or in musical terms, pitch, dynamic, timbre (tone color), and duration.

What are the 2 types of sound?

Sound has two basic forms: acoustic energy and mechanical energy . Each type of sound has to be tackled in their own way. Acoustic energy or sound is what we experience every day. It is in fact vibration of air (sound waves) which is transformed by the tympanic membrane in the ear of human to audible sounds.
