Rechner für Erstreflexionspunkte

Ermitteln Sie symmetrische Erstreflexionspunkte an den Seitenwänden mit der Spiegelquellenmethode und realen Raumkoordinaten.

The side-wall markers come from the mirror-source method. They identify geometric specular paths at seated ear height.

Funktionsweise

How to use it: enter the speaker and listener coordinates measured from the front wall, plus each speaker inset from its side wall.

Method. Each speaker is mirrored across its adjacent wall. A straight line from listener to mirror intersects the real wall at the first reflection point.

Example. In a symmetric 4.2 m room, both wall points occur at the same distance from the front wall.

Vor Verwendung des Ergebnisses

  • Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
  • Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
  • When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Einschränkungen

This solves horizontal specular geometry only. Speaker directivity, toe-in, ceiling and floor paths, seat width, panel size and absorption bandwidth matter. Confirm with a mirror test or measurement.

Häufig gestellte Fragen

How large should a panel be?

The point is only a centre reference. Panel size should cover movement across the listening area and the relevant speaker radiation, with practical mounting tolerance.
