Sound Environment Design and Consulting

Your requests for space design highly considered for sound environment and your ploblems of noise and sound utilization for spaces, we could support you with innovative ideas, acoustic technology and project excecution skills.

Sound environment design

Sound environment design means creating more functional, enjoyable spaces and facilities from the perspective of the sound environment by solving problems related to sound and noise, which we unconsciously withstand.
Sound environment design requires total consideration of different aspects in the planning, designing, and operations of facilities. These range from tangible aspects including the shape and materials of a building and PA system to intangible aspects such as words used in announcements and sound used for creating a certain atmosphere (Figure 1). Sound environment design can therefore also be called total coordination of the sound environment.
Utilizing our technologies for designing sound environments, we create and implement attractive sound environments based on innvative ideas created by design thinking, with project excecution skills (Figure 2).

Applicable range

  • Commercial facilities (e.g., Yokohama Bay Sheraton Hotel & Towers [Figure 3])
  • Sport facilities (e.g., Nissan Stadium (International Stadium Yokohama) [Figures 4 and 5])
  • Event spaces and amusement facilities
  • Customer facilities (e.g., Tokyo Tower observatory [Figure 6])
  • Airport terminal buildings and key public transportation facilities
  • Medical, welfare, and nursing-care facilities
  • Art, science, and other museums
  • Designing of acoustic facilities, PA systems, and all types of control facilities
  • Designing of sound for transmitting information (such as sound signals and audio guidance)
  • Designing and production of sounds for creating specific atmospheres

One of sound’s roles is to transmit information to people. Information obtained from sound is especially important for the visually impaired. Yet since sound simultaneously transmits information to a large number of people, it can be nothing but noise for those who do not need this information.

There is a notion of reducing the scope of application of barrier-free design by changing the "standard". We can say that one of the effects of universal design of a sound environment is making guiding sounds easier to perceive by reducing peripheral noise rather than making the sounds louder, thereby clarifying the guiding sounds as the information source buried within the noise (Figure 7).

According to our design and consulting flow (Figure 8), we utilize wide range of acoustic technologies and our wealth of experience in sound source software production to provide consultation on creation of sound environments with barrier-free and universal design suited to each subject space.
