Listen at the right time
An empty office on Sunday may sound very different on a working morning. Whenever possible, visit at a comparable time and day to the planned shoot. Listen for traffic, neighbouring businesses, deliveries, school playgrounds and public announcements. A short visit will not reveal every recurring event, so ask the building manager about the normal daily pattern as well.
At each proposed position, stop talking for a moment. Listen to the background, then ask someone to speak several sentences at a natural level. The relationship between voice and surroundings matters more than the general impression that a room is quiet. A short test recording also gives the director and production team something concrete to review after leaving the location.
Separate controllable noise from fixed conditions
A refrigerator, fan or air-conditioning unit may have a straightforward solution, but an authorised person must approve any shutdown. Do not disable equipment responsible for safety, essential operations or proper storage. Agree who controls the equipment, how long it may remain off and who will check that it is restored. These practical details belong in the production plan.
Traffic and construction usually offer no convenient off switch. Options include another time, a room on the opposite side of the building, closed windows or a framing change that allows closer microphone placement. When the location cannot be adapted, state the limitation clearly. Assuming that post-production will repair everything does not replace a decision about the required dialogue quality.
Check reflections and working space
A large glass interior can add substantial reverberation to speech. Moving a microphone closer often improves the balance of direct sound and reflections, but framing, lighting and movement constrain its position. A useful sound recce therefore considers the intended composition instead of testing a microphone in an arbitrary position in the middle of the room.
Check where the boom operator can work, where cables can run safely and whether there is a practical position for the sound equipment. For a location with several rooms, consider access and moves between setups. An available power socket does not automatically make a suitable workspace. Coordinate power requirements, weather protection and safe movement with production and the competent location personnel.
Leave with a short action plan
Record each problem, the proposed response, the person responsible and the point at which it will be checked. For an interview beside a window, the response might be moving the chair, scheduling shorter blocks between busy periods or reserving an alternative room. Document the limitations that remain, too. The director can then judge whether a very quiet, intimate delivery suits the real conditions.
Confirm these arrangements shortly before filming. Building operations may have changed, or another crew may now share the space. When enquiring about production sound, send the address, an outline schedule, the number of speakers and location photographs. This allows the recordist to ask more useful recce questions and identify situations where an in-person visit would be especially valuable.
Compare the cost of proposed measures with the cost of moving. An apparently inexpensive location may consume more crew time if every answer needs complicated scheduling. Conversely, a simple change of interview direction may preserve both the visual intention and the budget. Record at least one realistic alternative and establish the deadline for production to secure it.
