noise measurement data Applications

  • Noise monitoring solutions for data recording and analysis

    Brüel & Kjær provides a wide range of data recording hardware from pocket-sized units to 1000+ channel systems enabling you to: Save time with simple setup and an intuitive user interface. Save money by ensuring valid data. Record data with 1 to 1000+ channels. Raw time data is the key commodity for any measurements. Analysis can be performed at leisure, provided the actual data is safely recorded. For post-processing the data, PULSE Reflex software then provides powerful analysis capabilities. Simultaneous real-time analysis during data recording ensures that results can be checked, re-analysed and reported to other users – providing an important backup.

    Sound instrumentation for environmental noise monitoring

    State of the art noise monitoring systems; Modern noise monitoring systems offer a wide range of advanced features and come with software that can analyze and structure long term measurements data efficiently. A complete noise monitoring system consists of one or more noise monitoring terminals, a noise server and work stations for presentation, post processing and reporting.

  • Environmental Noise Monitoring

    The XL2 Sound Level Meter provides the dedicated solution for monitoring environmental noise in industry and communities. It measures levels and detailed spectral information in parallel and stores the data on an SD card for post-processing and reporting. A linear audio file (wav-file) may be recorded for detailed simultaneous analysis. The type approved class 1 sound level meter offers a flexible handheld instrument with accurate and reliable measurements. Data recording can be scheduled to occur at pre-determined times or automatically triggered when pre-determined levels are exceeded. Applications: Unattended noise monitoring stations (mobile or fixed installations) Annoyance assessment of noise according to ISO 1996-2 Construction noise measurements meeting the Section 61 notice (UK) Urban noise monitoring and noise mapping according to directive 2002/49/EC Verifying boundary noise level emission Advantages Handheld and compact design for field applications and stand-alone oper

  • Low frequency noise analysis using XL2

    The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data. The new features are particularly useful in the calculation of immission levels which is defined as the cumulative noise energy to which an individual is exposed over time. Exposure to low-frequency noise over extended periods can lead to a range of health problems including cardio vascular disease, insomnia and depression. The sources of low frequency noise can often be attributed to electricity sub stations, chiller plants and incinerators with continuous noise at frequencies below 200 Hz. XL2 Sound Level Meter records all Data Measuring LFN requires a class 1 sound level meter
