Abstract EN
This work introduces an economic solution for the problems of sound insulation of recording studios.
Sound insulation at wall resonance frequency is weak.
Instead of acoustical treatment, a digital filter is used to eliminate the effects of wall resonance and coincidence phenomena on recording of speech.
Sound insulation of studio is measured to calculate the wall resonance frequency and the coincidence frequency.
Pole / zero placement technique is used to calculate the IIR filter coefficients.
The digital filter is designed, simulated and implemented.
The proposed system is used to treat these problems and it is shown to be effective in recording the noisy speech.
In this work digital signal processing is used instead of the acoustic treatment to eliminate the effect of noise at the studio wall resonance.
This technique is cheap and effective in canceling the noise at the desired frequencies.
Experiments show that this technique is very effective in improving the sound insulation at wall resonance as well as at coincidence phenomena.
Field Programmable Array (FPGA) is used for implementation of the proposed filter structure which provides fast and cheap solution for processing real time audio signals.
FPGA is an attractive choice for implementation due to its advantages.
The implementation is carried out using Spartan chip from Xinlinx achieving higher performance than commercially available software solution.
