Airport, public malls, and governmental spaces for individual services are all spaces where public announcement occurs. The announcement of the flight number and timing requires a clearness in the speech to understand the announced information. Otherwise, the disruption and the distraction are the results. Similar results could happen in the public spaces as malls or governmental facilities (**Figure 8**). Acoustic design plays a different role in creating a masking background to clear the

Interior acoustics support the well-being of the users. The design of the spaces that require a sound quality needs specific elements to embolden the acoustical quality. The interior acoustical elements involve and interlace with other acoustical fields. These elements start by the space layout, which should be architecturally created to the specific function to prevent any basic problems. Otherwise, the interior solutions could cover such deficiency. The selective materials are the essence of the interior acoustical design. The interior treatments, quality, and position play the main role in the excellence of the acoustical functionality. It is a pure interior design, although the architect and especially the architectural acoustician consider it, to a very recent date, architectural treatments. The acoustical sound systems come as the third element as it is the additional element to any acoustical interior, for specific targets. If the acoustical interior design reflects the user's function, the acoustical engineering solutions presented through the sound systems should have a

The sound design, as a background, affects the users unconsciously. It could contribute to the psychological mood of the users. Human is productive while listening to his/her favorite music by 30%. The type of sound background—or

Sick peoples are the top users of quiet spaces where they take their recovering period. Museums are the place for specific levels of emotional entertainment or educational session; both of them are a relatively individual requirement and need high quietness levels. Classrooms are the spaces where instructors and students met for the educational processes environment. All these spaces (**Figure 6**) do require the best level of quietness background to achieve their specific functions. Hospitals, museums, and classrooms need a quiet environment. Such acoustical needs require more than the interior material scheme, it needs the isolation treatments to reach the quietness level.

Recording studios, musical halls, and theaters are the locations of musical enhancement functions. Each of these areas needs different acoustical treatments to reach a vital level of sound. Studios need absorption layout to remove any reflection possible. While the musical halls, where live music takes place, requisite a mixture between the reflection and diffusing materials to reach the life feeling of sound without echoes nor masking of sound (**Figure 7**). Theaters are relatively difficult as
