the next start level is -30dBu and start offset is -5dB, the next frequency would be started at -35dBu. It is possible to connect and calibrate as many inputs to Smaart SPL as you’d like, monitoring as many locations as you have the hardware infrastructure to support. Smaart SPL provides a powerful and full-featured solution for monitoring, metering, and logging SPL but with a format and price point more accessible to users who don’t require the real-time frequency and impulse response mode analysis capabilities of our flagship Smaart v8 software. You will also need a microphone preamp/sound card to supply phantom power and gain to the measurement microphone. LS sensitivity proc. by reaching the maximum output level), the corresponding data point is set to the highest SPL measured for this frequency. Max SPL measures the sound pressure level a loudspeaker is able to produce at particular frequencies. dB reference switches the level display between dBV and dBU. load [Ohm] the nominal impedance of the loudspeaker is entered. Smaart SPL creates logfiles in .txt format, and can generate SPL Summary Reports for user-defined time ranges. Download Virtual Sound Level Meter for free. Mix engineers, System Technicians, Rental Houses, Venues, Festivals, Casinos, Churches, Night Clubs – anywhere audio levels must be accurately measured, logged, and reported. dist [m]. We have proven ourselves from the best side both in the field of car audio, among audiophiles and sound producers, and among fans of car racing and drag racing TrueRTA 's audio spectrum analyzer software shows you a detailed picture of what you're hearing in real-time, that is, as it happens. A maximum of four thresholds can be measured, to be specified as percentage of the fundamental. SPL offers end-to-end testing, measurement and reporting solutions across the entire hydrocarbon value chain. Rel. SMAART kommer nordover. 3-Day Smaart Operator Fundamentals, Riksteatret, Oslo, 1-Day Smaart Application Practicums, Riksteatret, Oslo, Quick access to configuration functions and logging actions from a single, intuitive control bar, SPL History timeline shows data collected over entire logged or live-logging event, At-a-glance display of all calibrated inputs, Expandable meter grid for unlimited user-defined SPL readouts, Primary (upper) plot shows SPL history of entire log event, Secondary plot can show multiple metrics simultaneously, Time Range feature to zoom and nudge a specific amount of time, enabling highly detailed reporting, A fully configurable Meter Grid is a dashboard for critical showtime metrics, View meters for multiple microphones in real time, Green, Yellow, and Red “traffic light” threshold controls for each metric, Connect to Smaart SPL’s integrated web interface via any desktop or mobile device on the network, Password protection option for access control, Monitor multiple input devices concurrently, Configure alarms for any or all calibrated inputs, Alarm events are flagged in timeline and noted in timestamped logfile, Visual indication of alarm events on meter grid (meter flashes for user-configured length of time), Classic metrics found on most sound level meters, Options for A-weighting, C-weighting, and Z-weighting (no-weighting), Octave (1/1 Oct) weighting for monitoring the SPL of specific Octave banded frequency centers, Useful for measuring compliance with noise ordinances and venue restrictions, Custom Leq lengths in seconds or minutes, up to 1440 minutes (24 hours), A-weighting, C-weighting, Z-weighting, and Octave weighting, Noise exposure measured directly as a percentage of daily recommended dose, Exposure models based on NIOSH Recommended Exposure Levels and OSHA Permissible Exposure Levels, Smaart SPL logs 13 common metrics by default, Additional metrics can be customized/added as desired. Smaart SPL provides a powerful and full-featured solution for monitoring, metering, and logging SPL but with a format and price point more accessible to users who don’t require the real-time frequency and impulse response mode analysis capabilities of our flagship Smaart v8 software. Pause time [s] on the other hand is inserted as level independent break after each new frequency. Meaning it can be installed, and running simultaneously, on two different computers (or installed on one computer with one installation reserved as a back up in case of emergency). when measuring with the microphone on a rigid floor by -6dB for regaining free field conditions. This project is the MATLAB development of a virtual sound level meter. In Nom. Active loudspeakers for example are connected here. If this value is chosen too optimistically, the loudspeaker might be destroyed! Then add the measurement microphone, … Level increment describes the increment between two particular measurements. Using this value, the maximum recovery time will be reached earlier, but at low levels the measurement is still fast. SPL-LAB - manufacturer of measuring equipment . Max voltage rel. You can create your own professional measurement system starting with TrueRTA software on your PC. Smaart SPL’s intuitive and easily readable interface makes professional level SPL monitoring readily accessible to anyone using a macOS or Windows based computer system. Unlike Smaart v8 and Smaart Di v2, once activated on a computer Smaart SPL cannot be deactivated and moved to another computer. The report is generated for whatever time period is defined in the SPL History plot. Spl-Lab is a company operating in the measurement equipment and software market. With the built-in webserver, it is possible to ‘log-in’ from any device connected to the same network as the host computer running a copy of Smaart (SPL or v8) with inputs actively logging SPL data. Under Nom. In this case, Start offset will be added to the relative start level of the next frequency. When using external amplifiers, the correct specification of the amplifier gain in the Frontend setup is essential. Key Features Simple Streamlined Interface. The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. Smaart SPL offers the same complete SPL measurement toolset from Smaart v8 in a purpose-built standalone package, with an interface designed for simplicity and speed. If for Mic. The distance between microphone and loudspeaker is entered in Mic. power [W] the maximum power for the measurement is to be defined. Logfile header contains Max values for each logged metric as well as any Overloads, Alarm instances, and user-added Notes. Distortion thresholds are the THD limits evaluated during the Max SPL measurement. makes the measuring level fall back to Rel. amplifier defines the maximum measuring power when using the internal output stages of the frontend or external power amplifiers. Max SPL. The measuring signal consists of sine bursts, whose level is increased successively while SPL and harmonic distortions are being measured. Then add a measurement microphone and USB interface and you have a full audio/acoustic test setup. You do not have to purchase Smaart SPL separately. Analytical services provide valuable insights into your assets—enabling you to make more informed decisions, optimize production, and improve marketability. The hardware requirements are the same as other offerings in the Smaart platform. Copyright © 2020 SPL INC. All Rights Reserved |, Accurate, Defensible Data-Where You Need It, When You Need It. Of course, reports can only be generated for inputs that were, or are, actively logged or logging. If a particular measurement is stopped before reaching the threshold (e.g. Digital compliance tools provide handheld, real-time access to samples, data reporting, and trend analysis, as well as a full production allocation offering to keep you in compliance. For general measurements where Class 1 or 2 Compliance is not a requirement – any user supplied microphone suitable for acoustic test and measurement may be used, in conjunction with an SPL calibratior. Now the maximum measuring level can be specified as Level [dB], in the form of an RMS voltage (Voltage Vrms) or relative to the digital maximum level (Level dBFs). If you own Smaart v8, and have updated to Smaart v8.4, you already have all of the SPL monitoring, logging and reporting capability available in Smaart SPL. Kurs på Stormen, Bodø i Oktober. Amp output allows switching between the use of internal or external power amplifiers. ... WinMF Measurement Software If you retire a computer, or in the case of loss, theft or catastrophic failure, you will need to contact Rational Tech Support to reclaim the installation from your license. Corrected by [dB] is used for shifting the measurement by a constant value, e.g. Recovery max@[dB] clips the recovery time at a level relative to the maximum level to the maximum recovery time.
