Исследователи и разработчики акустических систем в основном обращают внимание на два наиболее заметных с точки зрения слухового восприятия типа искажений, вносимых в акустический сигнал звуковыми трактами - частотные и нелинейные. Эффект переходных искажений, проявляющийся в субъективных тестах прослушивания при сравнении динамических громкоговорителей с совпадающими амплитудно-частотными характеристиками и отсутствием слышимых нелинейных искажений, до сих пор недостаточно описан в научных работах. В настоящем исследовании проведены объективные измерения динамических громкоговорителей и сформулировали субъективные признаки качества звучания для определения степени влияния электромеханических характеристик громкоговорителя на восприятие переходных искажений. Также в представленной работе сделана попытка определить количественные отношения между этими характеристиками и субъективными оценками.

The two most noticeable types of distortion in an audio signal path - frequency and nonlinear - are frequently analyzed by researchers and developers in terms of auditory perception. The effect of transient distortion, though insufficiently studied, is evident in subjective listening tests when comparing dynamic transducers with similar frequency response and no audible nonlinear distortions. In the present study was conducted dynamic transducer measurements and subjective evaluations to define the critical factors based on the dynamic transducer’s electromechanical characteristics that affect transient distortion and determined relations between the factors’ values and subjective scores.
