# acousticintervals

Version 0.1 (2026-11-12)

Duration-weighted acoustic interval tables and energy means for LaTeX.
Commands: \AcousticIntervalReport{LAeq}{60/60,60/70} and \AcousticIntervalMean{60/60,60/70}.

Requires LaTeX 2022-06-01 or newer and booktabs. No special fonts, shell escape, network access or platform-specific programs. Put acousticintervals.sty beside your document. Compile acousticintervals-doc.tex with pdfLaTeX for documentation and synthetic regression examples.

Input is a comma-separated list of duration/level decimal pairs. Intervals must be consecutive and non-overlapping with consistent weighting, microphone position and meter setup. Invalid inputs suppress the whole result. Results are not exposure, safety or legal assessments. Example values are invented, not product measurements.
