No blocking method discontinuity is identified inside the selected cycle span, but one or more longitudinal changes require explicit harmonization conditions before pooling.
Evidence provenance: Praxis automated inference from indexed CDC/NCHS evidence
Evidence signals: source-derived
Relevant boundaries: 1999-2000 → 2001-2002 · 2001-2002 → 2003-2004
Praxis harmonization actions
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.

Questionnaire
These next questions are about noise exposure at work. First we are going to ask about loud noise. Loud means so loud that {you/s/he} must speak in a raised voice to be heard by someone three feet away when not using hearing protection. After that we will ask about very loud noise. Very loud noise is noise that is so loud {you have/he has/she has} to shout in order to be understood by someone standing 3 feet away from {you/him/her} when not using hearing protection. {Have you/Has SP} ever had a job, or combination of jobs where {you were/s/he was} exposed to loud sounds or noise for 4 or more hours a day, several days a week? (Loud means so loud that {you/s/he} must speak in a raised voice to be heard.)
