Quick Answer
Coyote call sensitivity in open fields is influenced by wind direction, terrain features, and the call's volume and frequency range. Strong winds can disrupt sound waves, reducing the effectiveness of a call. Terrain features like ridges and valleys can amplify or muffle the call.
Environmental Factors
When calling coyotes in open fields during the daytime, the wind direction plays a significant role in determining the call’s sensitivity. A gentle breeze of 5-10 mph can be beneficial, carrying the call to a distance of up to 200 yards. However, a strong gust of wind exceeding 20 mph can render the call ineffective, dispersing the sound waves in various directions.
Terrain Features and Acoustics
The terrain features in the open field can also significantly impact the call’s sensitivity. A slight incline or a small ridge can amplify the sound, making it audible to coyotes at a greater distance. Conversely, a valley or a depression can muffle the sound, reducing its effectiveness. To maximize the call’s sensitivity, it’s essential to position yourself on a slight elevation, allowing the sound to carry further.
Call Volume and Frequency Range
When calling coyotes in open fields, it’s crucial to use a call that produces a volume of 80-90 decibels and a frequency range of 100-400 Hz. This range is within the coyote’s hearing spectrum, making it more likely to attract their attention. The volume should be adjusted accordingly to match the terrain features and wind conditions. For example, in a windy situation, a lower volume may be more effective to prevent sound dispersion.
