The player achievement of accuracy in the performance of skill in volleyball depends on many variables, including the audio and biomechanical variables, and the exercise methods used ,which are appropriate to the type of skill, and the skill of service can get a point directly, and the formation of difficulty on the future team to pass the ball correctly makes it difficult to implement the offensive plans of the future team, so the trainers have to find appropriate audio training and using all appropriate training aids.

The study aimed to develop weight exercises using the optical device to develop the audio response and the accuracy and speed of the service skill of the volleyball players, and to identify the effect of weight training using the optical device to develop the audio response and the accuracy and speed of the smash service skill of volleyball players.

The study hypothesis is that there is a positive effect of weight exercises using the optical device in the development of the audio response and the accuracy and speed of the smash service skill of the volleyball players.

The researchers used the experimental approach with the design of one set of pre and posttests, (12) players and the player was excluded to become the total number of sample (10) players.

The results showed a positive development in the speed of motor response to the sound and speed of smash service skill of the research sample due to the use of special weight exercises using the optical device to develop the audio response.

The researchers recommended the use of instruments and tools in exercise because they have a significant impact on the development of the accuracy and speed of the auditory motor response of the smash , stressing on the use of weight training using the optical device to develop the auditory response to other technical skills, and the need to conduct audio tests in the selection of volleyball players according to specialization, the need for the attention of trainers in audio training because of their significant role in the development of technical and basic skills in volleyball, and Conducting a similar study of the auditory motor response and all other skills.
