Because of noise problems associated with pusher
installation with propeller operating in the wake turbulence of the
trailing edge of the wing, extensive noise testing was carried out.
Although noise level and intensity was found the same as for the 3 bladed
propeller the noise pattern on the 2 bladed is of a more pleasant lower
frequency. Noise level inside the cockpit during cruise was reduced from
108 to 95 dB.
