    corrections are shown below Octave Band Centre Frequency Hz 63 125 250 500 1k 2k 4k 8k A frequency weighting corrections 26 16 9 3 0 1 1 1 The A frequency weighting suggests that if a tone of 40 dB is played at 1000 Hz a 40 dB tone played at 63 Hz would sound 26 dB quieter or be 14 dB A Due to its simplicity and convenience the A frequency weighting has become popular and is now used for many different noise sources at different levels In fact most legislation regarding noise is written using dB A s in addition nearly all manufacturers of fans and other noise generating machines quote their noise levels in dB A s at 1 1 5 or 3 metres assuming spherical distribution It is therefore important that we understand the A frequency weighting and how dB A s are calculated Information on Fan Noise Test Standards Where noted in the product data pages within this catalogue fan noise levels are tested to BS848 Part 2 1985 Fans for general purposes Methods of noise testing This test standard describes methods that may be applied to calculate the sound power level of fans That is the In Duct method the Reverberant Room method and the Free Field method The sound pressure level of a product is measured using one of these test methods A calculation is then used to convert the measured sound pressure levels to sound power levels A Cautious Word on the use of dB A Levels The dB A sound pressure level is used almost universally to describe the noise level of many items of noise emitting machinery However published dB A sound pressure levels should be used for comparative purposes only they are not designed to reflect actual installed noise levels The assumptions that are used to calculate the dB A are rarely replicated in real life situations and therefore published dB A values will not necessarily represent the actual noise levels that may be experienced on site In order to determine the actual dB A sound pressure level that may be expected from an installation an acoustic analysis of the system using sound power levels and taking into account the surrounding acoustic environment should be performed Calculating dB A Noise Levels Published dB A or A frequency weighted sound pressure levels are theoretical values These are in fact calculated from the sound power level data and are quoted at a specified distance i e 1 1 5 or 3 metres For example using the Fantech model AP0804AP10 23 duty 7000 l s 80 Pa inlet side by applying an A frequency weighting correction to the fan sound power levels for each frequency and then logarithmically adding the values from left to right the resultant overall sound power level for this unit will be 98 dB A A further calculation is required to convert this value from the A weighted sound power level to an A weighted sound pressure

  • Fantech - Do’s and Don’ts
    the fan and ensure they are taut The air to the impeller tips is then not obstructed allowing the fan to operate to its optimum and minimises noise generation Close Duct restrictions at fans Ducts significantly smaller than the fan diameter create turbulence if transitions connect directly to fan Duct restrictions at fans Ducts significantly smaller than the fan diameter create turbulence if transitions connect directly to fan Don t An abrupt duct expansion at fan inlet causes air separation from the duct starves the impeller tips creates turbulence reduces performance and generates increased noise Do Duct expansions on the inlet to axial flow fans should be avoided where at all possible If essential the transition should have an included angle of not more than 15 Close Turning vanes at sharp bends Fit turning vanes in elbows adjacent to axial fans Turning vanes at sharp bends Fit turning vanes in elbows adjacent to axial fans Don t Eccentric flow conditions at both inlet and outlet will result in part of the impeller being starved of air and the fan not operating satisfactorily Do Square to round transitions and turning vanes in elbows assists uniform airflow this is a compromise only and by no means ideal Close Isolating vibrating fans Vibration transmission through building structures is a frequent problem Isolating vibrating fans Vibration transmission through building structures is a frequent problem Don t Do not bolt fan directly to the building structure as noise and vibration can be transmitted directly in to the building fabric Do Isolate fan and duct from the building structure with fan on neoprene or spring isolators and suitable flexible connectors Close Guards Safety of personnel around rotating machinery is crucial Guards Safety of personnel around rotating machinery is crucial Don t Don t leave open fan inlets unguarded This is unsafe to personnel and machinery In addition it may be illegal and leave the building owner or installer open to prosecution Do Ensure open fan inlets are fitted with suitable guards These should be designed to comply with local regulations and not only protect against injury but lessen the risk of a foreign object entering the fan and causing damage Close Obstructions at fan inlet Don t obstruct fan inlet Obstructions at fan inlet Don t obstruct fan inlet Don t The impeller can be starved of air when the inlet to the fan is obstructed This effectively increases the system resistance thereby reducing the air flow being handled by the fan Do Allow a gap at least equal to 1 fan diameter between the fan intake and nearby obstructions even then fan performance can be less than rated Always fit an inlet cone on open intakes Close Obstructions at fan outlet Don t obstruct fan outlet Obstructions at fan outlet Don t obstruct fan outlet Don t When the discharge is too close to a wall the obstruction generates noise and increases discharge losses Do Allow a gap of at least one fan diameter between fan outlet and obstruction and fit a diffuser on the discharge Close Transitions Ensure symmetrical transitions from duct equipment to fan inlet Transitions Ensure symmetrical transitions from duct equipment to fan inlet Don t Poor airflow little or no airflow through top of coil Do Centralise the fan to ensure uniform airflow through the coil Close Air flow dead zones Unducted air extract fans require careful location to obtain an even airflow across the room Air flow dead zones Unducted air extract fans require careful location to obtain an even airflow across the room Don t Part of room is starved of ventilation air Do Because of cross flow ventilation air circulation and quality of ventilation is optimised Close Roof ventilator short circuiting of air Ensure the roof ventilator base has an airtight seal Roof ventilator short circuiting of air Ensure the roof ventilator base has an airtight seal Don t If the unit does not have an airtight seal between the base and the upstand short circuiting of outside air can occur thereby reducing the amount of air being exhausted from the building Do An airtight seal between the upstand and fan base prevents short circuiting of outside air ensuring the fan is exhausting from the designated space Close Prevailing winds Mechanical roof ventilator units perform best if influence of prevailing wind is minimal Prevailing winds Mechanical roof ventilator units perform best if influence of prevailing wind is minimal Don t Unit above ridge is exposed to crosswinds Exhaust capacity may be reduced due to back pressure effects Do Roof unit relatively sheltered from prevailing winds suffers less from back pressure effects Close Back draft shutters Butterfly back draft shutters on a roof unit should be installed so gravitational effect on each leaf is the same Back draft shutters Butterfly back draft shutters on a roof unit should be installed so gravitational effect on each leaf is the same Don t Don t have shutters at 90o to roof fall The lower shutter must overcome a greater gravitational effect for even air flow Also the top damper may go over top dead centre and not close Do Each leaf has the same gravitational effect when shutters are parallel with roof fall Close Mounting of Roof Units to ductwork Mounting of Roof Units to ductwork Don t Don t connect to the eye of the base as this increases pressure losses on the intake Do Size inlet duct to fit roof unit overflashing Close Transitions Transitions Don t Abrupt transitions immediately adjacent to an attenuator will cause attenuator pressure drop to increase Do Ensure transitions close to attenuators are gradual or better still remote Close Volume control dampers Volume control dampers Don t Don t site volume control dampers or fittings too close to attenuators as they can cause a dramatic increase in attenuator pressure drop Do Allow for a setting duct between volume control dampers and attenuators Close Attenuators in relation to bends Attenuators in relation to bends Don
