A₄ is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A₄ in scientific pitch notation. It is standardized by the International Organization for Standardization.

 

The frequency  of this pipe may be slightly different after printing.

 

The pitch is affected by:

  • temperature
  • humidity
  • pressure 
  • altitude
  • chemical composition of atmosphere
  • printer accuracy
  • material shrinkage

 

Some conspiracy theories say that 440Hz is bad and it is better to use 435Hz or 432Hz. If you want to increase the frequency, print the pipe in a smaller scale by a few percent. If you want to lower frequency, print the pipe in a larger scale.
