What is an appropriate noise level for my library??

Noise can be an important factor in the quality of the experience enjoyed by patrons. If there are people in the library, then there is going to be noise. The key issue is to set standards for acceptable noise by area, then work to maintain the noise level to that standard.

1. Begin by purchasing a db sound meter. It’s difficult to set standards if there is no measurement tool. When we do Mystery Shopper studies, our Shoppers use a Digital Sound Level Meter. It is sold by Radio Shack, item #33-2055 and costs about $60. It is easy to use by anyone on staff.
2. Identify areas of the library that may be expected to have different noise levels. Monitor those areas for a week or two to develop a standard score.
3. Consider ways to start reducing the noise level in each area through the use of carpeting, wall hangings, acoustical tile, changes in blower velocity in heating and air conditioning systems, etc. As changes are considered and tested, it is relatively easy to evaluate the impact of the change with the db meter.
4. To achieve genuine quiet, areas or rooms may need to be designated as quiet rooms. Even in here, test the ambient noise level and consider ways to reduce noise as noted in para. 3.
5. Keep the children’s area separate (or away from) from the general reading area. As parents are reluctant to be separated from their children but may wish to look for materials of their own, using glass panels to separate a children’s area allows the kids to remain visible without impacting the noise level.

Although library staff work hard to avoid the stereotype of the “shussshing” librarian, the reality is that quiet/reduced noise environments are more conducive to reading, studying and most core library activities. The environment ends up playing a huge role in how quiet a library feels. From there, role modeling by staff and training customers can build the Library environment you want.
