Karting Land has entrusted Tafor Consulting with the acoustic design of the future FIA Homologated Karting Circuit, the biggest in Europe, which will be opening shortly in Palma de Mallorca.
The acoustic study of a 5* Hotel plus Auditorium and Convention Centre at Palma Beach was awarded to Tafor Consulting in May 2014.
Tafor Consulting has been commissioned to carry out the Acoustic Engineering Study of the Rafael Nadal High Performance Sports Centre, both with respect to the compliance of the Spanish Technical Building Code (Regulation) and also to the interior Acoustic Comfort and the noise control to exteriors. April 2014.
Tafor Consulting has carried out the Acoustic Study of the Marriott Port au Prince Hotel in Haiti for the American Resorts Company – our first project in the American Continent. April 2014.
Tafor Consulting has been awarded the Prize in Innovation as one of the first acoustic consultants, a pioneer in engineering methods developed to solve and avoid real noise and soundproofing problems while achieving the same acoustic insulation with much less material, enabling important savings in the constructions. December 2012.
Next July we will be opening our new Tafor Mexico office to start working with tourist sector companies and offices in the country.
As requested by some of our customers, we would like to give some basic concepts with respect to noise absorption requirements in the Acoustic Conditioning of indoor enclosures. We consider that it is important to know the main points related to the conditioning of enclosures, rooms or premises to obtain optimum Acoustic Comfort, with controlled reverberation, without background noise and good area sound coverage. These are summarized below:
- Acoustic Absorption is the property of a material to Absorb a certain percentage of acoustic pressure in each Reflection of the Incident Wave.
- A reflecting Closed Enclosure is a Resonator: it Amplifies the Noise, Diffuses it (diffuse field) and avoids Good Intelligibility.
- Absorbing Materials absorb via mechanical Elasticity, dissipating the sound pressure into heat: Rock Wool, Mineral Fibre, Fabrics, etc
- Each Enclosure, depending on the interior volume, will require a certain Absorbent Surface to obtain the Optimum Interior Acoustic Comfort (Reverberation, Background Noise, Sound Distribution or Sectorization).
- Noise Absorbing Materials also prevent the Noise Emission, because they avoid the amplifying of any generated noise inside the noise sources room, the noise emitted is controlled, and all of this is gathered without modifying the Soundproofing, which is the most expensive part of a Work.
As requested by some of our customers, we would like to give some basic concepts with respect to acoustic soundproofing and insulation requirements. Firstly, we consider that it is important to know the main points related with the soundproofing of a noisy room or premises. These are summarized below:
- Acoustic Soundproofing is the property of a material to Absorb a certain percentage of acoustic pressure in it’s Transmission through it.
- Insulating Materials isolate by Mass in Sealed Solutions: Plaster, Brick, Stone, Wood…
- A Soundproofing must be capable of Attenuating Interior Noise to control the Maximum Emission. The Soundproofing Index is a secondary and less important characteristic and has nothing to do with real noise attenuation.
- With Double Systems (Mass-Chamber-Mass) we obtain the same Soundproofing with Much Less Mass. We save by controlling the thickness of the chamber
As requested by some of our customers, we would like to give some basic concepts with respect to noise control requirements in noisy activities, such as musical, events, catering, hotel or industrial activities. We consider that it is important to know the main points related with tackling airborne noise and vibrations that are generated and diffused to protected areas, which we must protect in order to comply with environmental regulations or voluntary acoustic quality objectives. These are summarized below:
- Amplified Noise: each Soundproofing only supports up to one Limit. This limit must be known and controlled, for each frequency, and a sound limitation system must be installed to the Sound Amplifying Equipment.
- Facilities Noise: the Noise generated in outdoors requires a Barrier/Encapsulation system, and also by Mufflers or Absorbing Ducts.
- Vibrations: both in PA systems and in Machinery it is essential to prevent the Vibration from being transmitted to the building structure. Any Enclosure that vibrates in-tune will regenerate as a Membrane the PA or Machinery airborne noise. The manufacturer’s dumpers are Insufficient for residential areas.
As requested by some of our customers, we would like to give some basic concepts with respect to sound amplification requirements in leisure spaces, both indoor and outdoor. We consider that it is important to know the main points related to covering a space (open or closed) with sound or hi-fi music, so that it is heard with an optimum subjective intensity (signal to noise ratio of the ambient noise), and has a perfect coverage of the sound in the entire area of the public (sound distribution), and it is essential to carry out a detail study in order to prevent a sound time lag from one loudspeaker to the other, and above all, to avoid its overriding in space points for being in push-pull manner. Finally, the sound amplification quality of the sound equipment is also important, avoiding distortions and obtaining a high fidelity response of sound. These are summarized below:
- The first step is to always acoustically condition a space (Soundproofing + Comfort) in order to generate sound in the interior without modifying the sound spectrum. This avoids resonances or modes from the actual enclosure.
- Subsequently it is important to carry out a precision engineering study on how to fill or cover the space with sound: how many loudspeakers will be required, which acoustic power, what directivity, wich loudspeaker sensibility, and most importantly, how to fill the space with sound to obtain a uniform, high fidelity distribution.
- In terms of electro-acoustics, it is important to balance the sound equipment, avoiding sound time lags between the loudspeakers, avoiding signal distortions, etc.
- A good sound amplification is the last step in order to obtain perfect acoustics in an auditorium, night club, beach club, conference room, etc.
