HOW TO MEASURE A TRAILER
A trailer must be measured from the first audible sound of the trailer after the sync pop to the last sound, excluding any silence before or after. It must be measured on a TASA approved meter. The LeqM measurement is a whole number. Meters that include a decimal point in their measurement must be rounded to the nearest whole number — rounding up at 0.5. If you have any questions regarding the THX form, measurement, or process in general, please contact us.
