Da nazalost to sto se koristi na db drag krece sa cijenom od 400$ pa na gore al evo ti par opcija:
1. Najednostavnija, Digia SoundMonitor + Nokia ili Samsung (S60v2)
Program koristi mikrofon tel i prikazuje db, nije bas najtacniji ali za tvog eksperimentisanja moze posluziti.

3. Jos komplikovanija, ARTA Audio Measurement And Analysis Software + Laptop
Za profesionalnu analizu zvuka
Welcome to the home page of the ARTA software - a collection of programs for audio measurements and analysis in acoustical and communication systems.
The ARTA software consists of following programs:
ARTA - program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements.
STEPS - program for frequency response measurements with stepped-sine excitation.
LIMP - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.
The ARTA program has functions of following measurement systems:
Impulse response measurement system with signal generators: periodic white noise, periodic pink noise, MLS, linear and logarithmic swept-sine.
Dual channel Fourier analyzer with signal generators: white noise, pink noise, periodic white noise and periodic pink noise.
Single channel Fourier analyzer with signal generators: periodic white noise and periodic pink noise.
Spectrum, octave band and THD analyzer with signal generators: sine, two sine, multitone, white noise, pink noise, periodic white noise and periodic pink noise.
With calibrated microphone, ARTA can be used as a virtual IECC class 1 SPL meter with real time modes:
Integrating SPL meter with 24 hours data logging,
Octave SPL meter with noise rating (NR, NC, PNC, RC, NCB),
