To break it down:
- Train horns require compressed air to create sound.
- The PSI rating indicates the air pressure supplied to the horn.
- If you increase the PSI, you increase the volume and intensity of the sound.
- A higher PSI allows for a stronger airflow, which enhances the horn’s projection and clarity.
In contrast, a lower PSI results in a quieter, softer horn sound. The sound may be less distinct and less effective in signaling.
So, using the appropriate PSI rating is crucial to achieving your desired horn performance. Higher PSI generally yields better sound quality and intensity.
Why Is CFM Critical for Heavy-Duty Train Horns?
CFM, or Cubic Feet per Minute, is critical for heavy-duty train horns because it measures the volume of air that an air compressor can provide.
