Coworking or Home: A Month of Noise and Cost Measurements

A coworking desk cost 210 euros a month and reduced measured background noise from 58 decibels to 41, while increasing the number of interruptions from 2 a day to 11. The trade was not obvious before it was measured.

The comparison ran for a month in each location, same person, same work: technical writing with three calls a day and long stretches of concentration.

How noise was measured

A phone decibel meter recorded a reading every fifteen minutes during working hours, and the average was taken for each location. The numbers are indicative rather than calibrated, which is enough for a comparison between two rooms.

Home averaged 58 decibels, driven by street noise and a shared wall. The coworking space averaged 41, driven by a background of quiet conversation and ventilation.

Interruptions at home

Interruptions were counted as any event that stopped work for more than a minute and came from outside the task. At home this was two a day on average: a delivery, a neighbour, a household question.

The home interruptions were low in number and long in recovery, because each one involved leaving the desk.

Interruptions at the coworking space

Eleven a day, mostly conversational. A person passing the desk, a question about the coffee machine, two people who wanted to talk about a shared interest. Each interruption was short and the recovery was shorter, because the desk was still there.

Eleven short interruptions cost more than two long ones in total minutes, which the log showed clearly: 47 minutes lost at the coworking space against 22 at home.

The calls

Calls were better in the coworking space by every measure a listener can hear: lower noise floor, no deliveries, and a room that does not echo. Two colleagues independently said the audio had improved, without being told the location had changed.

There were also phone booths, which is the feature that made the difference and the feature home cannot have.

The cost, fully counted

The desk was 210 euros a month. Travel added 60 euros and 35 minutes each way, three days a week, which is 14 hours a month. Coffee and lunch added about 90 euros because the kitchen was no longer six steps away.

Total monthly cost was 360 euros and 14 hours, against a saving of about 25 hours of lost concentration at home. The two are close enough that the decision depends on whether the hours are worth more than the money.

What made the difference in the end

The deciding factor was not noise or cost. It was that the coworking space created a boundary. Work started when the desk was reached and ended when it was left, and at home both edges were soft.

The person now goes three days a week and works from home two, which is more expensive than either option alone and produces the best of both measurements.

What the month did not measure

Isolation. At home there was nobody to ask a question of, and two small decisions were delayed by a day each because of it. At the coworking space the same questions were answered in a corridor.

That value does not appear in a decibel reading or an interruption count, and it is the reason the hybrid arrangement survived the arithmetic.

Four months on

Three days at a desk and two at home. Calls are scheduled on desk days, deep writing on home days, which uses each location for what it measures best.

The cost nobody puts in a comparison

Working from a coworking space required a bag, a locker and a routine. The routine was the expensive part: 35 minutes each way is 70 minutes a day, and it was the reason only three days a week survived the arithmetic.

Home has no commute and no boundary, which is why it lost one comparison and won another.

Fifty-eight decibels and two interruptions at home, 41 and eleven at the desk. Neither is better. One is quiet and lonely, the other is noisy and connected, and the calendar now decides which is needed.
