Acoustics is a multidisciplinary field where many specializations cohere. The more the knowledge advances, the more the subfield growths and thus the belonging matter struggle. Acoustics comprehends a numerous profession such as architecture, engineering, physics, electronics, speech communication, mechanical engineering, medicine and speech communication, music and arts, and oceanography. Acoustics is a title, which today needs to be more complex as terminology, as all

Acoustics is associated until a near date to the engineering. However, nowadays,

The soundscape is the acoustics that deals with the unconscious effects of sounds

Acoustical environment is the interior design application of the sound behavior within the interior and the different physical reactions on the human functions. Acoustical oceanography is the study of the underwater sound. Acoustical engineering, like science, belonged to the engineering; then by the advancement of information, it splits to mechanical waves, where the science of sound and vibration across the technology exists. Acoustical engineering, as well, has a direct relation-

Interior acoustical design cooperates some of the previous elucidated aspects, the soundscape, the acoustical environment, and the electrical sound systems, where all are integrated into the interior spaces based on their functions.

Acoustics from Interior Designer

Should we consider the acoustics as engineering science or as architectural elements or as interior design applications? The main purpose of this chapter will focus on the differences between the three aspects of the acoustics with a special focus on the interior acoustical design. The arguments that favor the acoustic in each field are many. This chapter will clarify, strengthen, and explore the importance that has the acoustic study for the interior designing layout. From the historical eras where only material schemes were used, the acoustical treatment reached a great achievement. Nowadays, electrical, acoustical devices took place in different situations where only the materials could solve the acoustic needs. The considerations of using the electrical-acoustical devices remain under request, while their usage, only in
