Hemp vs.
Paper
by John Harrison, Inventor of the HempConeHemp is
a cellulosic vegetable fiber. It is renowned for its higher
strength and stiffness relative to wood based fiber (paper).
Once used to make marine ropes and tea bag paper! The higher
bending stiffness of hemp cones (relative to paper cones)
results in higher flexural rigidity. Higher bending stiffness
extends the cone's high frequency and operating bandwidth.
Hemp fibers are longer than paper wood fibers. The increased
fiber length increases the tear resistance as well as fracture
resistance of cones made from hemp. The speed of sound through
hemp paper is higher than through ordinary wood-based paper.
This decreases the phase difference between between sound
emanating from the cone apex and the cone edge. The decreased
phase difference means less sound cancellation and more
dispersion of acoustical energy.
By switching back to Hemp paper we could save our forests
and greatly reduce global warming and other problems created
by deforestation.
We at Brown have found that our Hempcones produce an
enhanced musical tone across the whole sound (sonic) spectrum
- tighter, warmer, fuller bass response. They have an unbelievable
transparency in mid range and a high end that has no ear
piercing properties. We're calling this new high frequency
response smoother and polished and super soothing to the
ear.
