摘要
A novel acoustic noise dosimeter is presented in this letter to investigate and measure the sound noise level that damages human hearing. A miniaturized magnetoelectric (ME) antenna is utilized to sense the sound noise level through the nonlinear antenna modulation around the operating acoustic resonance frequency of 63.6 MHz. Applied noise level of 102 dBA at two different 300 kHz and 1 kHz frequencies results in 33.8 dB and 28.7 dB signal to noise ratio. In addition, the fabricated antenna provides a high frequency of resonance of 2.49 GHz for energy harvesting and communications.
