Impulse response measurement system Single and Dual channel Fourier analyzer Spectrum, octave band and THD analyzer Triggered storage scope Two-channel voltage level meter and third octave analyzer With calibrated microphone, ARTA can be used as a virtual IEC class 1 SPL meter with a real time modes: Integrating SPL meter with 24 hours data logging, Octave SPL meter with noise rating (NR, NC, PNC, RC, NCB), Third octave SPL meter with report of specific loudness, loudness in sones and loudness level in phones. The ARTA program has functions of following measurement systems: Signal generator of following signals: white noise, pink noise, periodic white noise, periodic pink noise, speech signal, sine, two sine, multitone, triangle, square. LIMP - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.
