have a tricky noise or vibration problem you will probably consider
noise consultant or a vibration expert, but how do you decide whether the "expert"
really is an expert? Do they know the difference between a decibel and a
doorbell? When should you consult an expert? Well
British Standard 8233 Annex D is
entitled "special problems requiring expert advice", and when designing
the following you are recommended to consult an expert
- Acoustic Test Rooms
- Performing Spaces such as theatres, opera houses and similar
- Broadcasting and recording studios
- Aircraft noise
- Ground-borne noise
- Low-frequency noise
- Active noise control
- Noise Surveys.
your Noise Expert
Firstly you should probably look for membership of a professional body.
Its not to say that the above are
the only suitable professional bodies, for example when undertaking an
occupational noise assessment, a member
of an Occupational Hygiene Professional Body might be appropriate, but
there are many occupational hygienists who know nothing about noise!
Equally you should ensure that your noise expert has experience of your
problem. For example many members of the IoA work in the field of
underwater acoustics (SONAR) and would not be much help when trying to
reduce noise from a night club.
Probably the best guide would be to get any firm or individual to
forward details of their qualifications or experience, and then to check
that they measure up to the tasks which you have in mind.
The Advantages of Using a Professional Consultant
Professional organisations generally require members to
have minimum qualifications and experience and have
codes of conduct which require standards of behaviour including not taking
on work outside or beyond their fields of competence. The IoA Code
of Conduct can be read elsewhere. The ANC additionally
requires that member bodies do not have controlling interests held by
hardware manufacturers and that they should hold a given amount of
professional indemnity insurance.
