Chiller noise

We have a fairly small shop with 2 upright freezers, an ice-cream freezer and 2 chillers. When the compressors on the chillers are working the noise is quite loud and very annoying. We have all the equipment serviced on an annual basis and at our recent service the engineer said that there was nothing wrong with the chillers and they could last another 10 years or more.

Does anyone have a similar problem and have they found a solution?
