You can silence a piezo buzzer significantly by stuffing it with foam, resulting in a noticeable drop in decibel levels. However, this may require some fine-tuning to achieve an optimal fit. To get started, wrap your piezo buzzer in tape and then insert the foam, making any necessary adjustments to ensure a snug fit.
