Over The Air Reconfiguration through the cloud. The software includes an oscilloscope and spectrum analyzer features, as well as email alarms. Its highly sensitive Type 1 MEMS microphone has a noise floor of 30 dB-A, and is ultra stable with time and temperature variations. It is enclosed in a completely weatherproof casing which is designed for indoors and outdoors applications. This all-digital design includes the A, C and Z weighting curves. Its very small size allows it to be attached to or embedded within the monitored equipment.Įvery Wireless Sound Level Meter Data Logger NSRTW mk3 purchased is provided with an Individual Manufacturer’s Certificate of Calibration from Convergence Instruments. Connected to an external USB charger it can record and report for months. Running on battery, it can record sound pressure levels and report them through WiFi™ for a week. It includes a digital MEMS microphone, an accurate date/time clock, a non-volatile 128 Mb recording memory and wireless connectivity. Before we look at how the decibel meter evaluates the sound level and what is exactly loud and what is quiet in decibels, we first look at what is a sound wave and its main characteristics.The Wireless Sound Level Meter Data Logger NSRTW_mk3 is the third generation of Convergence Instrument’s WiFi™ enabled smart integrating sound-level meters/dataloggers. Just as it is difficult to find a place where you can clearly see the starry sky, it is increasingly difficult to find a place where it would be pleasantly quiet. In addition to light pollution, noise pollution is very common in today's world. On the other hand, no one probably wants to live in the midst of loud noise, as it can have devastating effects on both physical and mental health. According to the Guinness Book of Records, the quietest room in the world is located in the Orfield Laboratories in Minneapolis, and the longest time spent in that room is 45 minutes. We are already so used to sounds and noise that complete silence can actually scare us. Like electromagnetic waves, we are surrounded by sound waves almost everywhere and all the time, unless you are somewhere in a very exotic place. In the same way, sound waves moving in the air carry energy, and we can measure them with a decibel meter. In a previous post, we looked at a device that allows you to measure the energy of electromagnetic waves. A decibel meter, or sound level meter, is an electronic gadget that measures the level of sound or noise.
