By all reasonable accounts,
the move from traditional phone lines to VOIP
(Voice-Over-Internet-Protocol) voice communication has
thus far been driven by cost reductions or feature
flexibility.
That is, people have moved to VOIP to save money or gain
features. While audio quality was a concern that was
always mentioned, it was relegated to being a secondary
factor in the decision making process. As long as VOIP
could deliver sound quality that was comparable to the
quality of the voice communications delivered by an
ordinary telephone, it was considered to be acceptable.
Unfortunately, that mode of thinking was an
acknowledgement that while technology has advanced at
breakneck speeds in almost every aspect of the modern work
environment, telephone technology remains essentially the
same the copper wire based system that it was in the
1930s.
Now, with the advent of HD Voice (sometimes called
Wideband Audio), a change appears to be on the horizon.
VOIP is finally poised to offer, savings, features, AND an
improvement in the audio quality of voice communication.
With HD Voice audio quality could become a major
consideration in fueling the exponential growth in the
VOIP market.
At the heart of the change is an increase in Frequency
Response. Although technology has a bad reputation for
talking over the heads of an audience, an explanation of
frequency response can be made very easily and clearly.
Think of listening to music on an AM radio versus hearing
the same song on an FM radio. Because of better frequency
response the ability to reproduce higher highs and lower
lows FM radio outperforms AM radio for musical
reproduction.
The traditional copper-wired telephone, tied in to the
public switched telephone network (PSTN), has frequency
response that is even more limited than AM radio.
For the statistically minded, the Frequency response of AM
Radio is 40Hz 5,000Hz; Traditional telephone frequency
response is 33hz 3,300Hz; HD Voice is
30 hz 7,200 hz; and FM radio is 30 to 15,000Hz. While HD
voice doesnt approach the toanl quality of FM radio, it
surpasses that of AM radio and easily doubles the range
available in the telephones we have known all our lives.
For most of the last 80 years, limited response was
adequate. But now, as business becomes more global with
speech patterns and dialects more diverse, better call
quality is becoming an essential component in clear and
effective voice communication.
For most of us, even in telephone conversations with
someone whos first language is English, it can sometimes
be difficult to distinguish B from P or F from S.
But, the standards need to be higher for conversations
with multi-national clients and vendors, when the
difficulties are magnified and the competitive stakes are
much higher.
Whether we typically think in these terms or not, the
telephone is the single most important productivity tool
in any business environment. With HD Voice, a significant
improvement is now available for that most basic of office
tools.
