Полезная модель относится к устройствам для контроля средств защиты от шума или подавления шума и может быть использована при исследованиях свойств средств индивидуальной защиты, применяемых при организации защиты от шумового воздействия. Основу стенда составляет манекен головы, внутри которого в держателе установлены микрофоны, ориентированные в направлении ушных проходов с перекрытием сечения отверстия в держателях, что исключает проникновение звуковой волны в зону за микрофоном. При выполнении держатель, выполненный в виде единого конструктива, располагается внутри манекена головы таким образом, чтобы занимать пространство между зонами расположения ушных раковин. При этом держатель может выполняться из пластичного материала, способного демпфировать колебания корпуса манекена под действием звуковой волны, падающей на всю поверхность манекена головы, что обеспечивает снижение влияния этих вибраций на микрофоны. Для выравнивания давления между зоной закрытого средствами индивидуальной защиты ушного прохода и внутренним объёмом манекена предусмотрены капиллярные каналы. Технический результат заключается в обеспечении возможности исследования свойств индивидуальных средств защиты от шума в условиях, приближенных к реальным условиям применения. 3 з.п. ф-лы, 1 ил.

A sound pressure assessment system determines sounds to be presented by referring to a database retaining data of sounds, each of which is a pure tone. The system presents the determined sound as a first sound, and in a predetermined time after presenting the first sound, presents as a second sound a sound at least having the same frequency and the same sound pressure level as those of the'first sound to the user. The system extracts an amount of change from an N1 component in response to the first sound to that in response to the second sound. The N1 components are negative components of an user's event-related potential based on points of presenting the first and second sounds as respective starting points. The system determines whether the sound pressure level of the presented sound is excessive to the user, based on the amount of change. 1.
