Hearing losses, recording

Chapter 1 discusses the implementation of improved cochlea implants. Such implants seeks provide aid to those who have suffered hearing loss, a problem which impacts over 36 million people. This work seeks to improve the process through which the implants are constructed, moving from wire-based systems to microfabricated electrode arrays, which provides highly localized stimulation and recording of the neural tissue. In addition to it, electronics and sensor integration enhances working performances with added functionality. 

Recording criteria for cases involving occupational hearing loss. 15... 

Do I have to record the hearing loss if lam going to retest the employee s hearing ... 

If a physician or other licensed healthcare professional determines the hearing loss is not work-related, do I still need to record the case ... 

When you enter a recordable hearing loss case on the OSHA 300 Log, you must check the 300 Log column for hearing loss. 

Noise-induced hearing loss is a serious and irreversible condition. However, it is not the type of occupational injury that typically requires days away from work for recuperation. Beginning January 1, 2003, record work-related hearing losses of 10 decibel shifts that result in a total 25 decibel shift above audiometric zero. 

NOTE OSHA has revised the 300 Log and 300A Summary to include a check box and corresponding field specifically for occupational hearing loss cases. Beginning January 1, 2004, record these cases by checking the hearing loss column on the OSHA 300 Log. 

If a physician or HCP determines that the hearing loss is not work-related or has not been significantly aggravated by occupational noise exposure, you are not required to consider the case work-related or to record the case on the 300 Log. Examples include hearing loss occurring before the employee was hired or those unrelated to workplace noise, such as off the job traumatic injury to the ear or infections. 

If a standard threshold shift (STS), defined as an average of 10 dBA or more at 2000, 3000, and 4000 Hz, occurs in either ear, the employer must follow certain procedru-es outlined in the standard, including notifying the affected employee in writing. Hearing loss cases that meet specific criteria must be recorded on the OSHA 300 log according to the recordkeeping requirements of 1904.10. 

Final rule establishes criteria for recording work-related hearing loss. 

No. 1910.95 does not require the employer to prepare a written hearing conservation program. What is a recordable hearing loss ... 

A recordable hearing loss is one that indicates a STS of 10 dB from the baseline in one or both ears and the total hearing level is 25 dB or more above audiometric zero, averaged at 2000, 3000, and 4000 Hz in the same ear(s) as the STS. 

Until 2004, occupational hearing loss was recorded as part of the Other category on the OSHA 300 Log. OSHA then added a hearing loss column to the 300 Log so the Bureau of Labor Statistics (BLS) could produce more reliable statistics on documented occupational hearing loss cases (66 FR 6005). 

New recordability rules also redefined a recordable hearing loss from the previous definition of an average 25 dB change in hearing at 2000,3000 and 4000 Hz as compared to the baseline audiogram to the current definition outlined above. 

Employers should seek additional tools to help ensure their workers are not exposed to noise levels that can contribute to a recordable hearing loss. New technologies and tools train employees on positive hearing conservation behaviors and document such company efforts. 

There is very little information on road traffic collisions affecting some of the most vulnerable road users for example, people with disabilities and equestrians. Police STATS 19 data do not routinely record whether someone is visually impaired, suffers from a hearing loss or is a wheel-chair user. Until 2000, data were not collected on horses involved in road traffic collisions.
