英文摘要	The impact of noise made by vessels on marine animals has come under increased concern. However, most measurements on noise from vessels have only taken into account the low-frequency components. For cetaceans operating in the mid-and high-frequencies, such as the Indo-Pacific humpback dolphin (Sousa chinensis), mid-to high-frequency noise components may be of more concern, in terms of their potential impacts. In this study, noise made by a small high-speed boat was recorded using a broadband recording system in a dolphin watching area focusing on the effects on humpback dolphins in Sanniang Bay, China. The high-speed boat produced substantial mid-to high-frequency noise components with frequencies to >100 kHz, measured at three speeds: similar to 40, 30, and 15 km/h. The noise from the boat raised the ambient noise levels from similar to 5 to 47 decibels (dB) root-mean-square (rms) across frequency bands ranging from 1 to 125 kHz at a distance of 20 to 85m, with louder levels recorded at higher speeds and at closer distances. To conclude, the noise produced by the small high-speed boat could be heard by Sousa chinensis and therefore potentially had adverse effects on the dolphins. (C) 2015 Acoustical Society of America.
