The Windjammer adds further
protection against noise caused by wind, than that of a standard single
windshield alone.
The standard (basket) windshield shows up to
25dB wind-noise attenuation at 35Hz while giving almost no signal
attenuation. Adding a Windjammer will give an improvement of some 10dB
at LF - 35dB.
The attenuation of the Windjammer is
approximately 5dB at frequencies above 6kHz although this will increase
if it is damp or allowed to get matted. Overall this combination gives
the best performance of wide-band wind-noise reduction against signal
attenuation.
