($28.95 ATA Members / $29.95 Non-Members)

MotoSafe Natural Sound Plugs are designed specifically for driving situations. Utilizing two custom filters, MotoSafe works by reducing volume evenly across all audible frequencies (see chart below). You can clearly hear your your radio, voices, warning signals and traffic without distortion, at a reduced, comfortable volume. MotoSafe plugs are also excellent for music applications.

Average Attenuation Values
  Hz 125 250 500 1000 2000 4000 8000
Green Filter (blocks less sound) dB 14.8 15.0 15.7 18.7 26.6 24.4 18.9
Yellow Filter (blocks more sound) dB 18.8 15.6 16.0 18.5 27.7 28.9 22.0
Note: On the dB (decibel) scale, which is a non-linear scale, a 10 dB reduction in volume is perceived as half as loud, so the difference in loudness between the two filters will be perceived as a 25-40% difference in loudness, depending on the particular frequencies (Hz) present in the sound being heard.
