A series of EPA studies of environmental hazards problems associated with energy emissions leads to the conclusion that the previously developed powerful ultrasonic devices and systems with the use of electronic components and low degree of integration could have been potentially dangerous to human health. The updated concept of using ultrasonic devices is aiming at reducing the possible harmful radiation related devices, firstly, through the reduction in unit capacity of ultrasonic devices and the choice of technology-specific ultrasound parameters sufficient to implement the process. Secondly, an improvement in safety is achieved by using modern element bases and the performing the corresponding changes in circuit design of ultrasonic generators and waveguide design, application of modern schemes of automatic stabilisation modes and emergency protection. It has been experimentally proved that the number of multi-function devices can be designed not to cause harmful emissions and energy fields – a decent example of Hilsonic can be considered – the company focusing on production of complicated ultrasonic cleaner equipment; the technological processes and approaches practised here ensure unparalleled safety of the ready products.
The fact should be also underlined that the process of ultrasonic technologies integration in many industries, such as processing of raw materials, is a factor that significantly reduces the supply to the process of operation of other energy flows, and thermal energy in particular. The environmental benefits of this need no proof. Finally, the intensification of many processes, for example in the field of ultrasound extraction reduces and total exclusion from the reaction mass number of extract-ants recognised as harmful to the environment. For example, with the ultrasonic extraction of oil from sea buckthorn pulp withdrawal of CFCs from the process becomes real.
Thus, the ultrasound technology with hardware-based multi-function low-power generators in many respects can satisfy the requirements of salvage, resource-saving, environmentally friendly processes and provide a more efficient compared to the traditional methods use of natural resources.
However, a final conclusion about the environmental safety of ultrasound should be done as long as the factors of its direct effect on living organisms are considered and a confirmation received that ultrasound systems do not break the flow of information of natural systems and do not create emissions dangerous for the existence, development, reproduction and adaptation of living organisms. Therefore, the analysis of environmental security should continue to study the factors that determine the risk of the use of ultrasound in direct contact with the person. This task is part of the more general problem of analysing the effectiveness of technical solutions to meet the requirements of environmental protection and environmental management at the stages of design and testing, because at the present time, science has become a productive force, resulting in the emergence of a new source of harmful effects on the environment – scientific – technical activities of man. One of the problems that must be addressed in the development of technical solutions, is the problem of the classification of the possible adverse effects on the severity and irreversibility, and, accordingly, the necessary measures should be taken to prevent them.
