A method for reducing noise in a towed acoustic array includes providing a towed array having a length, diameter, frequency range and tow speed. The relationship between tension in the towed array and wall pressure fluctuation spectral levels is determined. Wall pressure fluctuation spectral levels are related to the noise in the array. An optimal towed array tension is calculated using the determined relationship. Tension is increased to the optimal towed array tension by either provided additional towed array hose or a drogue at the end of the towed array.
