The A34 runs from Salford to Winchester. The Southern leg of the road cuts through Oxfordshire from North to South. The soundscape at Drayton FC to the East and Milton United FC to the West of the road is dominated by the sound of the internal combustion engine; the resonating tarmac; and the rattle of trailers and trucks . Drayton FC play in the North Berks League and their pitch is on the South-West edge of the village. The centre circle is 175m East of the A34. If you stand in the centre-circle – where this recording was made – there are benchless breeze block dugouts; a line of low trees; and an electricity pylon that stands in the field between the pitch and the road. The embankment of the A34 rises above the field and the sounds of the road flood down the embankment and saturate the surrounding area with a band of consistent high frequency noise. The rattle of trucks; the phasing of tyres on asphalt as they approach and depart; the liquid drone of the road – these are the sounds that dominate the listener’s attention.
Milton United FC play at Milton Heights which sits above the Milton interchange of the A34. I made this recording from the centre circle of one of the two pitches on the site which is 370m South-West of the A34. The sound here differs radically from that at Drayton. There is more local detail and a more varied frequency range. There is a sense that we are listening to sounds from farther afield – that this is an auditory vantage point. If I turn my head to the South I can hear the road as a high frequency drone – a more distant sound; if I turn to the North-East I can hear a more complex sound – a greater range of frequencies that includes vehicles slowing and braking as they exit the A34. There are sounds that are closer by too – trucks sit in the lane that leads to Milton Heights; the president of the club is painting white lines and at times we can hear this as the wheels of the line marker work against each other and the paint moves from wheel to wheel before it makes contact with the grass.
