The Hawks Nest

Whilst 2020 has, unfortunately, seen many venues have to close their doors, there have been a few new ventures giving it ago and during Christmas last year we were asked to consult on an exciting, trendy new venue in Shepherd’s Bush London: The Hawk’s Nest. 

A wicked concept; outdoor cocktail bar meets pizzeria, the Hawk’s Nest consists of an indoor area and outdoor covered seating area full of flowers and vast wall art in an open and covered seating area. 

Running parallel to the railway line, to the west of the Hawk’s Nest at a higher level is a block of flats. The flats were the nearest residential dwellings and were unsurprisingly at risk of being disturbed by patron noise.

Challenge

An outside venue looking to achieve planning permission, needing to control the general hubbub of people noise in a relatively residential area of West London, with close proximity to flats in the height of the Covid-19 pandemic.

Solution

MAL16 marquee acoustic linings to line the roof of the structure and contain noise within the covered seating area.

Result

Planning and license permission granted and the continuation of a successful business relationship.

Data Gathering

To get a handle on the level of work required to combat any noise pollution and to help us analyse and suggest a mitigation strategy, Direct Acoustics gathered underlying data when the venue was open and when it was closed. Over the 10 hour period that the venue was open, an average 64.8dB L​Aeq was established compared to over the same period when the venue was closed, an average of 51.5dB L​Aeq. 

To meet reasonable internal bedroom target levels as set out by World Health Organisation (WHO) of 35dBA LAeq and considering their statement: “It should be noted that it should be possible to sleep with a bedroom window slightly open (a reduction from outside to inside of 15 dB)”  the goal for The Hawk’s Nest was to not exceed an average of 50dB L​Aeq and the property facade during the venue’s operational hours.

Mitigation Measures – Marquee Acoustic Linings

Considering the 15dB broadspectrum reduction required, Direct Acoustics proposed the implementation of our MAL16 acoustic linings to be installed into the roof and gable ends of the existing marquee. As the structure of the marquee was constructed within two large brick 4m + walls, linings were not needed in the walls, unlike typical marquee set ups.

Once the lockdown had lifted, it was happy drinking for the punters of West London!

About Our Marquee Acoustic linings

The acoustic linings that we manufacture are highly proficient at containing sound within any structure. The MAL range which we used at The Hawks Nest is specifically designed for and fabricated to slide directly into the structural frame of the marquee. This lining provides a high degree of control to non-amplified sounds such as the laughter, cheering and chinking of glass found in any bar.

We manufacture our acoustic linings in two weights dependent on the sound reduction required:

MAL16 (2.6kg/m2) – 16dB Rw

MAL22 (6.9kg/m2) – 22dB Rw

The composite make-up employed utilises both absorption and mass to create the most effective acoustic marquee lining available. After spending years researching and developing sound solutions, Direct Acoustics now manufactures our own line of acoustic and thermal linings at our workshop in Sussex. The linings are unparalleled in the industry and have undergone UKAS accredited lab tests to identify their frequency specific sound reduction index.
