    Notes: A concept and an implementation of the multimedia computer system for the monitoring of environmental noise is presented in the paper. The system provides an extension to the Internet-based system for testing hearing which was engineered and launched in 1999. A considerable portion of hearing diseases is caused by excessive industry, urban and traffic noise or any unwanted sounds occurring in everyday life. Consequently, it is expected that a reduction of hearing diseases occurrence will be achieved as a result of implementation of the solutions that have been developed within the project scope. The latest technological advances in information technology were used in the course of the project realisation. Consequently, it is shown in the paper that the presented solutions are based on some innovative ideas and inexpensive technical means for measuring noise and vibration allowing fast evaluation of its influence on the psychosomatic and the vegetative system. It is expected that implementation of the noise telemonitoring system covering whole country will contribute to rising awareness of society and authorities with regard of the influence of noise on health. Furthermore, it turns out to be an essential factor in the future improvement of the environmental noise conditions.

    Notes: Abstract. In lidar measurements noise and fluctuations strongly affect the results. The reason is a rapid decrease of the signal-to-noise ratio with an increase of distance. The differential absorption lidar (DIAL) is particularly sensitive to the signal instabilities. In this paper we present a method of the signal acquisition that is suitable for registration of both large light fluxes and single photons. We also present new method of solution of the DIAL equations. Compared to the traditional algorithm used for signal elaboration our procedures are much more stable and they are able to increase the effective range of lidar measurements.
