The results of an investigation of an unusual vibration problem in a Diesel-engined ship are presented and discussed. When this ship approaches the shore or passes through a narrow channel, houses located within 350 m of the ship's funnel experience low frequency noise of over 65 dB and there is a chattering noise from the glass windows. Measurements of the low frequency noise spectrum at various locations on the ship are presented graphically. A relationship between sound peak level at 20 Hz and the distance from the top of the funnel is derived. Order from BSRA as No. 51,065.
