The dB display PCE-SLM 10 is suitable for the continuous measurement and visualization of the sound pressure level. The PCE-SLM 10 dB display is used in schools, open-plan offices, bars, clubs and other event venues. Due to the large digits of the dB display, the measured value is always easy to read. Due to the LED display, this is also possible in dark environments without any problems. The dB display is powered by USB with the optional AC adapter or external battery pack.

The measuring range of the dB display ranges from 30 ... 130 dB. The sound level meter displays the measured value A weighted. The time weighting of the dB display is always Fast. The frequency range of the 6 mm condenser microphone ranges from 31.5 Hz to 8.5 kHz. The dB interface can be connected to the PC via the USB interface. The software can be used to transmit live measurements to a computer. The dB display also has an internal memory, which can be read out with the software.

Contamination of the environment is a topical and controversial modern issue. Different methods of how to improve the situation are offered, and, though many may be surprised by that, noise is one of the items in the long list of the harmful factors. Acoustic contamination is not visible and it is difficult to evaluate the level of it at once, but its impact on the health is tremendous. With the help of the modern auxiliary devices, like noise warning indicator, it has become possible to keep the level of noise under control and take immediate measures if the values go beyond the permissible threshold.

The advantage of acquiring and application of the noise warning indicator is that it does not require any special training and knowledge. The values displayed on the screen are easy-to-read and the device lets the people, present in the premises under supervision, to know about harmful deviations form the norms by itself. The noise warning indicator can be installed anywhere and due to its small and elegant design will fit even in the most demanding interior. This makes the application of the device versatile and widens the range from the industrial workshops to offices and even private areas.

The compact noise warning indicator can be applied anywhere, where the noise level, at different times of the day and night must be monitored and kept under control. Besides, since it is quite handy and portable it may be used for demonstration with the educational purpose. It is very easy to show the reaction of the device to the rapidly increasing noise, due to the immediate response. For each particular area, like school, kindergarten, hospital, library, public place, office, meeting-room, canteen, hall etc there are different noise level safety norms. The task of the operator is to set the required limits in the device and carry out the necessary adjustments. The noise level is not stable and permanent and tends to fluctuate a lot depending on the amount of people present, time of the day, presence of the influencing factors like music, radio, traffic sounds, noise from the construction site near-by, telephone ringing etc. Continuous application of the noise warning indicator allows for careful study and monitoring of the situation over a certain time period, which gives sufficient information for making conclusions about how appropriate this or another place is for the purpose it is currently used for, or for making plans for the future if it goes about choosing the place for some new establishment.

Noise warning indicator plays such a positive role that can hardly be overestimated, in spite of its small size and simple design. Its application helps any organization, company, institution and even private individual comply with the safety norms and regulations of the Health organizations.

The workers who have a chance to look at the device during the day may make conclusions themselves about the level of noise they are exposed to and regulate the situation in the favourable for them way (talk quieter, reduce the telephone ringtone volume or carry out the rearrangement of the working places in one room). Nowadays many people complain about stress; noise is one of the most harmful factors which may cause excessive emotional burden, and application of the device may help a lot and contribute to the creation of a better and healthier working atmosphere.

Those sectors where people are subject to continuous noise, due to their professional activities, cannot refuse from the noise warning indicators at all. As against to the example above, some types of noise, especially at the enterprises and construction sites are inevitable. In these cases, the noise warning indicator gives immediate indication that urgent measures of precaution, like hearing protection, must be worn.

In the public places, like libraries, auditoriums, schools, even recreational places and centres, noise level control is more difficult to control, since there are many people involved and there are much more additional influencing factors. Noise warning indicator enables to analyse the situation and introduce the new rules of behaviour or carry out additional changes in the schedule so that to reduce the noise pollution for the common positive purpose.
