 This paper presents and discusses the acoustic measurement results of four different alert whistles that produce sounds through airflow and the investigation results of reactions of sika deer (Cervus nippon) to alert sounds played from a vehicle mounted loudspeaker. The acoustic measurement of the alert whistles revealed that the basic acoustic characteristics of these whistles are similar, and it was confirmed that these whistles produce sounds of approximately 3 kHz, which are similar to deer alarm calls or sounds of approximately 17-18 kHz. However, none of the sounds could be confirmed in the measurement experiments while the vehicle was running. The investigation of the sika deer reaction to the alert whistles sounds confirmed that the sika deer provided a vigilant reaction to the sounds of approximately 3 kHz and to those of deer alert played back through a loudspeaker.
