Final answer:
The disadvantages of using a linear transducer can include limited frequency response, non-linear distortion, elevated noise floor, and low power output, affecting its performance in various applications.
Step-by-step explanation:
Linear transducers are devices commonly used in a variety of applications from medical ultrasounds to distance measurement. One disadvantage of using a linear transducer is the possibility of a limited frequency response. This means the transducer may only operate effectively within a narrow frequency range, potentially making it unsuitable for applications requiring a broader frequency spectrum. Additionally, non-linear distortion may occur, where the output signal does not accurately represent the input signal, particularly at higher amplitudes. Another drawback could be an elevated noise floor, which means that the level of background electrical noise is higher, possibly affecting the transducer's ability to detect weaker signals. Lastly, low power output might be an issue, which could limit the transducer's range or its ability to detect objects that are farther away. It's important to note that these disadvantages are general and can vary based on the specific design and application of the linear transducer. A sound wave is emitted, which reflects off an object to measure distance, and is dependent on the constant velocity of sound. However, underwater, the intensity of sound is perceived differently, as acknowledged by Navy research, which suggests that sound is heard through vibrations in the mastoid bone behind the ear.
