The tapping machine HD 2040 is a normalized impact noise generator for the measurement of sound insulation of floors according to the following standards: ISO 10140-5:2021 - EN ISO 16283-2:2020. It has 5 hammers in line driven by a motor controlled by an electronic system, by means of camshaft. The rate of fall of the hammer and the frequency of the impacts are constantly monitored to ensure compliance with the legislation. LED indicators on the front panel indicate the proper functioning of each hammer, detected by an optical sensor. The hammers are made of stainless steel, hardened and dimensionally stable over time. The unit is equipped with support feet with height-adjustable rubber base. The reference spacer for drop height verification is fitted on the back cover. The starting and stopping of the machine is via a front panel button or remotely using the supplied remote control. Mains power supply 100...240 Vac or rechargeable lithium-ion battery housed inside the unit. The charger is built; the battery recharges automatically when the machine is connected to the network. The aluminium frame reduces the weight of the machine and makes it easily transportable.
HD2050 is a sound source composed of 12 speakers arranged in a dodecahedral chassis, capable of radiating high power sound energy in all directions with a directionality in accordance with ISO 3382. The sound source can be integrated with the digital amplification system HD2050.20, which offers high power as well as providing an equalizer that adapts the system's response to any more specific measurement needs.
HD2050.20 is a high-power digital amplifier; it includes a white and pink noise generator with wireless remote control. Thanks to the auxiliary input it's possible to drive it with an external generator to apply, for example, sine sweep signals.
The HD2050.30 façade loudspeaker is the ideal tool to generate a uniform soundfield on the front of a building. HD2050.30 provides not only the high output emission in a frequency range extended from 70 Hz to 20 kHz, which is necessary to minimize background noise contribution, but also a uniform sound distribution, especially at higher frequencies, which is guaranteed by the particular construction of the high frequencies driver.
HD2050.40 passive subwoofer is designed to work in conjunction with HD2050 dodecahedron. The system composed of HD2050.40 subwoofer, HD2050 dodecahedron and HD2050.20 digital power amplifier, allows to meet measurement requirements in the highest acoustic insulation situations.
