The organisation warns that some lighting fixtures create audible mechanical noise that interferes with dialogue recording

The Association of Motion Picture Sound (AMPS) has raised concerns about LED stages, saying that some lighting fixtures create audible mechanical noise that’s noticeable in the performance space.

It says that, in dialogue-critical scenes, the noise can be so loud it competes with the actor’s voice. The noise, says AMPS, masks subtle dynamics and compromises “the truthful capture of performance”.

AMPS adds that post-production tools can reduce the noise but can’t restore performance detail as it was never cleanly recorded.

It says that actors “deserve an environment that supports concentration, vocal control and emotional truth”. 

The organisation is calling on manufacturers and productions to treat acoustic neutrality as a fundamental requirement of lighting design. It says: “Silent or genuinely quiet operation is essential to respecting performance and preserving the artistic intent of the work. The human voice carries emotion, intention and nuance that must be captured live, in the moment, and without avoidable interference.”
