Our folks are partial to Peltor muffs.
Are there no ear plugs that meet your noise reduction rating criterion?

Subject: [DCHAS-L] Ear muffs
Hi all,
Some of the students in our biochemistry use a sonicator (Fisher Scientific Model 100 Ultrasonic Dismembrator). This sonicator emits a high-pitched sound. I know that in some labs, people wear ear muffs when using the sonicator. I think it would be the safest thing if our students also had ear muffs to wear when using this instrument. Any recommendation for an appropriate lab-safety type of earmuff?
Thanks,
Wayne
