Рассмотрены проблемы калибровки средств измерений инфразвуковых колебаний в атмосфере. Проанализировано влияние внешних условий – атмосферного давления, относительной влажности и температуры воздуха – на воспроизводимое в измерительных камерах пистонфона звуковое давление в диапазоне частот 0,001–250 Гц. Оценены погрешности расчёта звукового давления в измерительных камерах пистонфона при различных вариациях внешних условий. Приведены специальные требования к системе поддержания требуемых значений внешних условий.

The influence of environmental conditions on a sound pressure reproduced by the primary method in the measuring chambers of the Pistonphone in the frequency range from 1 mHz to 250 Hz is estimated. Numerical estimations of influence of environmental conditions on sound pressure in pistonphone measuring chambers are given and special requirements to system of maintenance of required external conditions are specified.
