Cinema
A commercial screen is isolated from its neighbour, tuned for a decay shorter than what is discussed for a concert hall, and seen from every row. A home cinema is a different construction project, not an equipment list.
What this gate is
Cinema on this gate is a room decision: isolation between adjacent Auditoriums, an RT60 criterion for the project rather than a universal number, a sightline to the image, then projector or LED cinema because the geometry allows it, not because fashion asks. The page claims no THX certificate and no invented accreditation, and it copies no fire classification or STC from a catalogue.
The commercial path is not the domestic path. A home fails when a bedroom shares the slab or when HVAC is the noise floor, and a loudspeaker name does not repair that. ISO 3382-1 is a measurement reference for performance spaces; using it in a house is stated explicitly. The local code remains the reference for fire and egress. This gate does not replace those documents.
What is published now
Commercial screen design
Isolation between screens, RT60 as a project criterion, sightlines, and projector versus LED.
Home cinema
Isolation from bedrooms, HVAC noise, bass, seating distance, and the limit of what a living room can become without construction.
What stays on other pages
Isolation detail, projectors, LED screens, and RT60 as a measurement subject. The gate directs and does not abbreviate.
What is not claimed
No brand certificate, no STC figure, and no city page for cinema complexes.
When to open this gate
Two or more screens side by side
When one film can be heard in the next screen. That is an isolation question, not an equipment question.
A domestic room wanted as a cinema
When it must be said early that the structure is shared, and whether the work is construction or an acceptance of living-room limits.
Wrong scope
A television upgrade in a sitting room with no isolation and no HVAC work, or a request for a brand certificate: both sit outside this gate.
How to read the subject
- 01
Separate the commercial path from the domestic path before choosing the image. Isolation and neighbours are not a final detail.
- 02
Write RT60 as a project criterion, usually discussed as shorter than a concert hall, with no universal number. Measure later by a stated method, and to ISO 3382-1 where its scope applies.
- 03
Draw the sightline to the image, not to a stage. A projector needs throw and a port; LED cinema removes the port and changes cooling and the sightline.
- 04
Do not call a logo on the equipment an accreditation of the room. The room is handed over on its measurement, its isolation detail, and the adopted code.
What this gate does not do
Swapping a projector for LED as fashion
The two images are different rooms. Isolation, sightline, and cooling do not travel with the name of the technology.
Copying an RT60 from the internet
What is discussed as shorter than a concert hall is a direction, not your project's criterion. The page does not set the seconds.
Wrong scope
The gate is not an equipment shop, not a certificate, and not a directory of screens in a city. Field isolation is not shortened to an STC written here, because the page does not write one.
Questions designers and owners ask
Is cinema RT60 a fixed number?
No. It is often discussed as shorter than a concert hall because dialogue and image do not want a long tail. The value is a project criterion, measured by a stated method. ISO 3382-1 is not replaced by this gate.
Does LED remove the isolation requirement?
No. The neighbour still hears if the wall, door, and floor are a weak path. Changing the image source does not close the path.
Why is a THX certificate not stated?
Because this gate grants no certificates and attributes no accreditation to a project. If an accreditation exists, it is a contract with another party and their documents, not a sentence on a knowledge page.
When does a living room stay a living room?
When there is no construction separating it from sleep, no independent air path, and no door that actually closes. Hanging a screen does not change that. The detail is on the home-cinema page.
Is a theatre sightline a screen sightline?
The method, including C-value, may be discussed, but the target is the edge of the image, not a stage. Geometry and code fix the number, not this gate.
Technical sources
- ISO 3382-1
Measurement of performance-space parameters. Whether it applies to a cinema or a domestic room is read from the standard's scope and stated in the brief. This gate does not replace it.
- The C-value method in planning literature
Sightline clearance over the head in front, often discussed around 90–120 mm in theatre literature. In a cinema the target is the image. The page does not replace the section.
- The building, fire, and egress code adopted by the project
Occupancy, exits, and the performance of finishes. The gate names no city and grants no product fire classification.
