² The noise pol­lu­tion re­gisters spe­cify:

a.

the noise pol­lu­tion meas­ured;

b.

the cal­cu­la­tion pro­ced­ure used;

c.

the in­put data for the cal­cu­la­tion;

e.

the sens­it­iv­ity levels ap­plic­able;

f.

the in­stall­a­tions and their own­ers;

g.

the num­ber of per­sons who are af­fected by noise ex­pos­ure levels above the ap­plic­able ex­pos­ure lim­it val­ues.

³ The en­force­ment au­thor­it­ies are re­spons­ible for the su­per­vi­sion and re­vi­sion of the re­gisters.

⁴ On re­quest, they sub­mit the noise pol­lu­tion re­gisters to the FOEN. The Of­fice may is­sue re­com­mend­a­tions on the stand­ard­ised re­cord­ing and present­a­tion of the data.

⁵ The Fed­er­al Of­fice for Civil Avi­ation is re­spons­ible for meas­ure­ment of noise ex­pos­ure levels pro­duced by Basel Mul­house Air­port on Swiss ter­rit­ory.

⁶ Any per­son may have ac­cess to the noise pol­lu­tion re­gister provided that con­fid­en­ti­al­ity with re­spect to man­u­fac­tur­ing and busi­ness secrets is en­sured, and no con­flict with oth­er in­terests that over­ride ex­ists.
