7: TECH TALK ON WOOFER BOX DESIGN
The rest of the BLAUBOX owner’s manual discusses, in detail, various
speaker related subjects including acoustics, electronics, and speaker
operation.
Screen 7 includes short, on-line help sections discussing these areas
so no further discussion of this screen will be made in this manual other

Most people can hear sound over frequencies of 20 Hz to
20,000 Hz.
A piano will reproduce sound from about 50
Hz to over 10,000 Hz in the harmonics.
We can hear sound over a huge range in Loudness. Most
people with good hearing can recognize sound as Low as
0 db, the
of hearing. At about 120 db perm-
anent hearing Loss occurs many rock concerts average

The 120 db range of
loudness represents a difference of
times a noise at 0 db!
Technically speaking, a doubling of amplifier power is
3 db, but the human ear often needs volume differences
of nearly 10 db to qualify a sound as
as Loud.
db is the smallest audible increment in loudness
Our ear requires significantly more bass for Low
frequencies to sound as loud as mids and highs at low
