Acoustic Testing 'Frequently Asked Questions'
Enclosed within this download are answers to some of the more
frequently asked questions in matters relating to acoustic
testing services provided by Air Pressure Testing <view
Building Regulations Approved Document E
Approved Document E of the Building Regulations (2000) came
into force on July 1 2003. It is designed to meet demands
for improved acoustic insulation and to combat the problems
of noise pollution from neighbours.
The Regulations apply to both new build and conversion or
refurbishment work and set out standards for; the sound insulation
of party walls and floors between dwellings (or rooms used
for residential purposes), the sound insulation of internal
walls and floors, the control of reverberation within communal
areas and the acoustics of schools (See Building
Bulletin 93). Approved Document E can be downloaded
The Regulations require the builder to undertake pre-completion
sound insulation testing of a sample of party walls and party
floors to demonstrate to Building Control that compliance
with Part E has been achieved. A series of Robust Standard
Details (RSDs), constructions that will provide the required
level of sound insulation with a suitable tolerance for workmanship
have been developed and adopted as an alternative to pre-completion
APT Acoustics can provide the following services in
relation to Building Regulations Approved Document E: design
advice, site inspections and UKAS accredited sound insulation
Building Bulletin 93 - Acoustic Design of Schools
The aim of Building Bulletin 93 (BB93) is to provide a comprehensive
guide for architects, building control bodies, building services
engineers, and others involved in the design of new school
BB93 gives the performance targets for compliance with Requirement
E4 from Part E of Schedule 1 of The Building
Regulations 2000 that 'each room or other space
in a school building shall have the acoustic conditions and
the sound insulation against disturbance by noise appropriate
to its normal use'. All school buildings must conform to BB93
and are subject to detailed design checks on on-site inspections.
The document BB93 can be found at www.teachernet.gov.uk/acoustics
APT Acoustics can provide the following services to
solve your classroom and school acoustic issues with relation
to BB93: noise surveys , design services and sound testing.
The Control of Noise at Work Regulations
The Control of Noise at Work Regulations which came into effect
in February 2006 replacing the previous Noise at Work Regulations
have been developed in order to comply with the European Union
Physical Agents (Noise) Directive (2003/10/EC) which aims
to protect workers from risks to their health arising from
exposure to noise. The document The Control of Noise at Work
2005 can be read at www.opsi.gov.uk/si/si2005/20051643.htm.
There has been a transitional period for music and entertainment
sectors which is now coming to an end and it is expected that
these premises will be compliant by 6th April 2008.
The Regulations give several "action levels", which
mean that if noise reaches a certain level, an employer must
take certain action.
The first action level is that of a daily average workplace
noise of 80 dB. If noise reaches this level, employers must
educate their workers as to the effect of noise and what can
be done to protect them. They must also provide and maintain
hearing protection for all the employees affected by the noise
level. The 2005 regulations also state that employers must
try to minimise the level of noise in the environment before
bringing in hearing protection measures. This can be achieved
through various methods, such as fitting noise absorbing panels
to reduce sound reflection or modifying equipment to make
The second action level is that of an average workplace noise
of 85 dB or a peak of 137 dB. These regulations state that
employers must enforce the use of hearing protection if workplace
noise exceeds this level. Hearing protection zones, where
workers must wear ear protection, must also be clearly marked
at this level of noise. Average levels must never exceed 87dB
nor peak at 140dB. This is known as the peak action level.
APT Acoustics can undertake occupational noise surveys
to verify compliance with the Control of Noise at Work Regulations.
The Control of Vibration at Work Regulations
The Control of Vibration at Work Regulations came into force
on 6th July 2005. The regulations apply to the exposure of
workers to both hand-arm vibration and whole-body vibration.
The Control of noise at Work can be read at www.opsi.gov.uk/si/si2005/20051093.htm
The Regulations require the employer to assess the risk to
health created by vibration at the workplace, to eliminate
the exposure or where this is not reasonably practicable to
reduce it to as low a level as is reasonably practicable.
In some circumstances the employer is also obliged to provide
health surveillance to prevent or diagnose any health effect
linked with exposure to vibration. In addition the employer
is also required to provide information, instruction and training
on the risks of vibration at work to their employees where
there is an established risk to their health.
APT Acoustics can undertake hand-arm and whole-body
assessments to verify compliance with the Control of Vibration
at Work Regulations.
Planning Policy Guidance 24
Planning Policy Guidance 24 Planning and Noise (PPG24) was
published in 1994 and aims to provide advice on how the planning
system can be used to minimise the adverse impact of noise
without placing unreasonable restrictions on development or
adding unduly to the administrative burdens of business. PPG24
can be read at www.communities.gov.uk
PPG24 provides specific guidance on the assessment of noise
on sites proposed for residential development and references
other suitable documents for the assessment of noise affecting
new or existing hospitals, road & rail traffic noise and
noise from aircraft together with noise from industrial sites
and the leisure industry.
APT Acoustics can undertake PPG24 assessments
It is strongly recommended you use a UKAS Accredited
APT Acoustics is UKAS accredited (4340) for Sound Insulation
Testing to Building Regulations Approved Document 'E'.
Sound testing is required by an UKAS Accredited (or similar)
company to show compliance with the Building Regulations Approved
Document E 'Resistance to the Passage of Sound' criteria.
Testing is conducted on party floors and walls which separate
dwellings from one another. Sound Testing is used to assess
the performance of the insulation and its associated flanking
Pre Completion Testing has been a mandatory requirement since
July 2003. All new build properties and conversions which
were built after this date require 10% of each party wall/floor
construction type to be tested. Testing is to be carried out
between pairs of rooms separated by party walls or floors,
in most cases the rooms to be tested will be the two main
habitable rooms which would be living rooms and bedrooms.
The test procedure involves setting up a noise source in a
room on one side of the party wall or floor and measuring
the noise on both sides of the partition.
APT Acoustics site testing is undertaken to a stringent internal
quality system following the guidance from ISO/IEC 17025:2005
General requirements for the competence of testing and calibration
The testing methods for airborne and impact sound insulation
is in full accordance with the suggested methods presented
in BS EN ISO 140-parts 4 and 7: 1998. The results of the tests
are analyzed in accordance with BS EN ISO 717 parts 1 and
