Broadcasting station (television, radio, distribution studios)
Functional layout of a broadcasting station
When planning a broadcast station, the most difficult aspect is the layout of the acoustic rooms.
Although the basic plan will be developed by the owner and the design office, it is beneficial to have a specialist to look over the layout from a functionality perspective with particular attention to ease of use. Nihon Onkyo Engineering regularly performs sound consulting in addition to interior design and construction from both the acoustic and the functionality viewpoints. Our record includes services provided throughout the country, from key broadcasting stations in Tokyo and Osaka to regional offices and community FM radio stations.
Characteristics of a TV studio
For a television studio, because the media being handled includes both sound and images, a cyclorama (large, concave background wall) is necessary for recording video in addition to sound recording. For music-oriented programs requiring high-quality recording capabilities, the cyclorama is often backed by lighting only for a simple set construction, which can lead to a reciprocating reflection of sounds from the opposing wall of the cyclorama.
To prevent such acoustic obstructions, performance-oriented construction techniques such as tilting the cyclorama horizontally or providing a mortar-shaped elevated cyclorama wall are required.
In large-scale broadcasting stations, multiple TV studios may also be positioned side by side or stacked on top of each other. In such cases, electromagnetic shielding must be ensured to ensure sound insulation performance between studios and to prevent crosstalk between headsets and the invasion of outside radio waves. To do so, the construction technique must combine both acoustic construction and shielding construction.
Characteristics of a radio studio
Radio programs are generally live broadcasts. As such, it is important to create a studio environment that allows announcers and guests to talk comfortably. This means ensuring balanced acoustics―from low frequencies to high frequencies―in limited space.
Radio studios also are not only limited talk and music playback but also live in-studio acoustic performances. As such, electromagnetic shielding work may be required depending on the electromagnetic wave conditions, as recording microphones are easily affected by external radio waves and may pick up and broadcast such radio waves.
Characteristics of a distribution studio
In recent years, communication companies and software development companies have begun planning delivery-only studios as content transmission bases within their company. Nihon Onkyo Engineering strives to meet a wide variety of needs ranging from specifications similar to large broadcasting stations that emphasize video and sound quality to more compact specifications that can be created in tighter places (such as one-room offices), for example, talk-based information presentations and CG playback.
