McLennan Sound Monitoring is a small company based in Eugene, Oregon that has been manufacturing sound level alarms since 1999. Their customers have ranged from farmers to those monitoring pressure build-up in gas well-heads, and they have listened to their needs to continually improve and add practical features to their product.
Their Mini-Mac Sound-Relay-Alarm is a sound activated device that triggers two relays when it detects a certain sound level. It is factory set to trigger at approximately 90dB, but can be internally adjusted for greater or lesser sensitivity to meet the needs of their customers.
The goal of the website is to showcase the many uses for their high-quality sound alarm, which can be purchased at a reasonable price.
