This Wall of Sound Always Annoys : Raiders: Los Angeles has lost six of its last seven games against the Seahawks in the Kingdome.

SEATTLE — Forget your houses of pain, mirrors, wax or the one Ruth built. The house the Raiders are not welcome inside is this one, the Kingdome, where games are measured by decibels, not points. Once, the Raiders practiced all week with stereos blasting, hoping to achieve a sense of deafness, if not deftness.

“If you could hear, it wouldn’t be a problem,” Raider Coach Art Shell said. “But when you start calling cadences, the tackles, they can’t hear.”

When you’re a poor road team to begin with, it only complicates matters. And the Raiders are a poor road team heading into today’s game against the Seattle Seahawks. The Raiders finished 1-7 away from the Coliseum in 1989, 1-5 under Shell. They are 7-0 at home under Shell.

The Raiders have lost six of their last seven in the Kingdome and four consecutive games overall to the Seahawks. Shell has looked long and hard for answers. He took his team on tour this summer, with stops as far away as London for an exhibition.

“It’s not psychological,” Shell said of his team’s problems on the road.

Then what’s the answer?

“You take them out in the preseason like we did, traveling to Chicago, traveling to San Francisco, and stress the importance of why you’re there,” Shell said. “You’re not on a social trip. It’s a business trip. That’s the only way you can approach it. Hey, we’re here for one thing--play, win the game and get the hell out of town. But we’re a different team this year, traveling, than we were last year. I really believe that.”

Fortunately for the Raiders, they will play a Seattle team that has been outscored, 46-0, in its last two regular-season games, dating to 1989. The Seahawks are a team in transition--a common football euphemism for potentially awful--and introduced their new “spread” offense in the opener last week against Chicago. Spread is another name for the run-and-shoot, although the Seahawks don’t run it exclusively, mixing it with their old Ground Chuck offense.

What the Spread did in last week’s 17-0 loss to Chicago was make a star of the Seahawks’ punter Rick Donnelly, who kicked nine times. Seattle totaled 132 yards on offense and never crossed the Bears’ 45-yard line.

Some are saying the Seahawks don’t have the quick receivers needed to make the spread offense work.

Shell is not saying that, however. “I’m not going to tell you where they failed,” he said. “Then, I’m telling you where I think the weaknesses are at. I’m not going to do that.”

Seattle Coach Chuck Knox said his team’s troubles could be attributed to flaws in execution, not design. “It just wasn’t the new offensive wrinkle,” he said. “It wouldn’t have mattered what offensive formation we were in.”

Sounds like the same problem the Raider offense is having. And Knox said the Raider defense is even better than Chicago’s.

“I was surprised because Denver has an outstanding team,” Knox said of the Raider domination of the Broncos. “It’s not very often that you’re going to shut down John Elway. The Raider defense was just outstanding. I think they’re definitely back.”

The Raiders relied on two defensive touchdowns to pull out a 14-9 victory over the Broncos.

The Raiders started that game with 12,070 rushing yards on the bench in Marcus Allen (7,275) and Greg Bell (4,795), opting to go with Vance Mueller and his total of 426 yards.

“Me and Marcus joked about that on the sideline,” Bell said.

Whatever the organization has against Allen, it apparently will not stand in the way of progress or potential points. Shell didn’t announce a starter this week, but Bell and Mueller predicted that Allen would get the start based on the tailback rotations in practice last week. Shell said he will continue to rotate his backs throughout the game.

Allen played briefly in the first half of last week’s game and didn’t take his first carry until the second half, gaining 28 yards on the play. Allen finished with 47 yards in eight carries, an average of 5.9.

Raider Notes

The one Raider who has fared well in the Kingdome, Bo Jackson, is still running the basepaths in Kansas City. Jackson set the team’s single-game rushing record with 221 yards here in 1987. In that game, Jackson had a 91-yard scoring run and averaged 12.3 yards in 18 carries.

Seahawk Coach Chuck Knox has had this rebuilding feeling before. “We went through rebuilding with the Rams in 1973,” he said. “We did it in Buffalo when we went there in 1978, and we did it here in 1983. It’s different in the fact we’ve had to rebuild a team that we’ve been with seven years. That’s been different.”

The Seahawks haven’t scored a point in 256 days, dating to a 13-yard pass from quarterback Dave Krieg to John L. Williams that beat the Raiders, 23-17, last Dec. 17. The next Saturday, they lost to the Washington Redskins, 29-0.
